What is Refractometer Critical Angle Measurement?

Vaisala refractometers use the critical angle measurement principle. A refractometer's three essential components are a light source, a prism, and an image detector. 

DOWNLOAD THE REFRACTIVE INDEX MEASUREMENT PAPER HERE

The light source sends rays to the prism and process interface at different angles. Rays with a steep angle partly reflect at the image detector and partially refract at the process. Low-angle rays reflect entirely on the detector. The angle from which the total reflection starts is called the critical angle. 

The CCD camera detects a bright and dark field corresponding to partly reflected and totally reflected light. The position of the borderline between the bright and the dark area correlates with the critical angle, which is a function of the refractive index and correlates with the solution's concentration.

A built-in temperature sensor measures the temperature T on the interface of the process liquid. The sensor converts the refractive index nD and temperature T into concentration units. 

Vaisala K-PATENTS refractometer can indicate different scales, for example, Brix, liquid density, or concentration by weight. The diagnostics program ensures that the measurement is reliable.

Calibration of a 4-20 mA Transmitter in a Hazardous Area Using a Portable Calibrator

This video demonstrates how to calibrate a 4-20 mA transmitter in a hazardous environment using a portable calibrator, in this case, the WIKA CPH7000 Ex.

Before you do calibrations in a hazardous (Ex) space, you must be aware of several things. There are many levels of dangerous areas, as well as various levels of calibrating equipment to choose. A hazardous location includes or may contain combustible substances (whether indoors or outdoors). It could be a liquid, gas, vapor, or dust that is combustible. Depending on the hazardous area classification, a flammable substance may be present all of the time, a particular percentage of the time, or just in specific instances, such as during shutdowns or accidents. 

In the best of circumstances, calibration can be a challenging task. Doing so in an area with a risk of explosion raises the complexity level to a new level, requiring the technician to have the necessary training and equipment. The WIKA CPH7000 Ex process calibrator is a precise, easy-to-use portable instrumentation calibrator that tests process transmitters in hazardous areas.

Pulse Burst Radar Level Transmitters

Pulse Burst Radar sends short bursts of energy to the surface of a liquid. The time it takes for a signal to be reflected off the liquid surface is measured by ultra-high-speed timing circuitry. 

Filtering out false reflections and other background noises is accomplished through sophisticated signal processing. The precise level is then calculated by taking tank height and additional configuration information into account. Because the circuitry is highly energy-efficient, no duty cycling is required, as with other radar devices. This enables the device to track rapid level changes of up to 4.5 m/minute (180"/min). 

Magnetrol uses Pulse Burst Radar for Radar level measurement rather than frequency modulated continuous wave (FMCW), which is today's more common operational technology. Pulse Burst Radar operates in the time domain and does not necessitate the complex and costly processing required for FMCW. 

Pulse Burst Radar is more efficient at sorting through extraneous echoes and selecting the one reflected by the actual level because echoes are discrete and separated in time. Pulse Burst Radar also has excellent averaging characteristics, vital in applications where the return signal is affected by the factors described in "Don't Forget the 3 D's of Radar" below. 

Unlike actual pulse devices, which send a single sharp (fast rise-time) waveform of wide-band energy, Pulse Burst Radar sends out short bursts of 6 GHz or 26 GHz energy and measures the transit time of the signal reflected from the liquid surface. The following equation is used to calculate distance:

Distance = C x Transit Time/2, (where C = Speed of Light)

The level value is then calculated by taking tank height and other configuration information into account. The sensor reference point – the bottom of an NPT thread, top of a BSP thread, or face of a flange – is the exact reference point for distance and level calculations. 

Remember the 3 D's of Radar 

Three fundamental conditions influence radar applications: 

• The process medium's dielectric; 
• The application's distance, or measuring range; and 
• A wide range of disturbances can weaken or distort the radar signal. 

Low dielectric media can weaken radar's return signal, reducing the effective measurement range of a device. Pulse Burst Radar provides accurate measurements even in low dielectrics. However, when the dielectric is extremely low, as with liquid gas, fuels, and solvents, or when boiling and/or flashing can occur, Guided Wave Radar (GWR) may be the better choice in radar technology. 

The distance, or measurement range, of Pulse Burst Radar, is determined by the antenna used, the dielectric constant of the medium, and the presence of signal interference. Turbulence, foam, false targets (interior tank obstructions causing false echoes), multiple reflections (reflections off the tank roof), and a frequent level change rate can all weaken, scatter, or multiply radar signals. Excessively high or extremely low liquid levels can also be problematic. 

The Processing of Signals 

Because radar exhibits interference effects similar to those seen in light, the signal processing function is critical. The quality of a device's signal processing is what distinguishes today's cutting-edge radar transmitters from the rest. 

Pulse Burst Radar extracts accurate levels from false targets and background noise through its sophisticated signal processing capabilities. Because pulse burst radar circuitry is highly energy-efficient, no duty cycling is required to achieve effective measurement. As a result, Pulse Burst Radar can track high rates of change that would be impossible to track with other loop-powered radar transmitters. Although Pulse Burst Radar has a robust false target recognition and rejection routine, proper installation significantly minimizes false target reflections. 

Antennas 

The radar signal is transmitted and received by the antenna on the transmitter. Each antenna's maximum measuring range is primarily determined by dielectric constants and the degree of turbulence. Horn antennas can measure dielectric media as low as 1.4, whereas rod antennas have a minimum dielectric of 1.7. 

Benefits 

Pulse Burst Radar measures a wide range of media accurately and reliably in a wide range of process conditions, from calm product surfaces and water-based media to turbulent surfaces and aggressive hydrocarbon media. As a non-contact device, Pulse Burst Radar is immune to the complications that can occur when a probe comes into contact with the process media, such as coating from high viscosity media or corrosive attack from aggressive chemicals. Given the cost of extended probe lengths, the greater the measuring range, the more radar proves to be the cost-effective solution. Temperatures, pressures, the presence of vapors, and air movement within a vessel's free space have little effect on the radar. Specific gravity, conductivity, and dielectric constant changes do not affect measurement accuracy. The lack of moving parts in a 100% electronic instrument translates into low maintenance costs, and, as a two-wire, loop-powered device, power requirements and installation are greatly simplified.

Magnetic Level Indicators and Controls for Industrial Process Applications

Fluid process control operations frequently involve the storage of liquids in a vessel or tank. The continuous and accurate indication of the liquid level within the tank is an important data point for process control decision making and safety. Several tank level measurement methods and instrument types are available, each with its own set of characteristics that may be advantageous for a specific installation. 

A tank liquid level indicator's selection criteria often include: 

• Does the process require direct or indirect measurement of level?
• What level measurement accuracy and reliability is needed?
• What is the tank shape, regular or irregular?
• Are there concerns with media compatibility with measurement device materials of construction?
• How often will maintenance or calibration be needed?
• Is the instrument capable of operating at the process temperature and pressure for the application?
• Does the application require local display and visibility or remote?
• Are control signals from the level indication required? What type and transmission protocol?
• What kind of redundancy and safety devices, such as additional switches, are needed?

Magnetically coupled liquid level indicators, or MLIs, are widely used in the process industry. They are accurate, consistent, and reliably indicate liquid level. These units are completely sealed and do not require any maintenance. MLIs also eliminate the vapor or liquid emission issues that plague sight and gauge glasses. 

Most Compelling Reasons for Using MLI's:

• Level measurement is continuous. 
• Operable without the use of electricity. 
• Regardless of tank shape or profile, they provide a direct visual tank fluid level indication. 
• They are available in wide operating temperature and pressure ranges. 
• MLI construction is resistant to breakage.
• A variety of materials are available to accommodate corrosive media. 
• Externally mounted measuring indicators, switches, and transmitters do not come into contact with the process media. 
• MLI's provide a continual operation that requires little maintenance. 
• The level indication is viewable from a greater distance than glass sight gauges. 
• With a single instrument, it is possible to measure large fluid level ranges.

Magnetic level indicators have a strong presence in tank liquid level measurement and should be considered a candidate for meeting those application requirements. There are numerous options for customizing the level indicator for each application.  Work with your local Sales Engineer,  a specialist in level measurement, about your application challenges and positive outcomes.
