Back Pressure Regulators

Back Pressure Regulators

An industrial back pressure regulator is a type of pressure control valve that is used to maintain a consistent pressure downstream of the valve in a process piping system. It is designed to allow fluid to flow in one direction and is typically installed in the outlet of a process unit or a piece of equipment.

The basic design of a back pressure regulator includes a main valve body, a control piston or diaphragm, a spring, and a control mechanism. The control piston or diaphragm is connected to the spring, which is adjustable to set the desired downstream pressure. The control mechanism, which may be a pneumatic or electric actuator, is used to adjust the position of the control piston or diaphragm in response to changes in the downstream pressure.

The main valve body contains an inlet and an outlet, as well as a flow passage that connects them. The flow passage includes an orifice, which serves as the main flow restriction. When the downstream pressure rises above the set point, the control piston or diaphragm moves to close the orifice, reducing the flow and bringing the pressure back down to the set point. When the downstream pressure drops below the set point, the control piston or diaphragm moves to open the orifice, increasing the flow and bringing the pressure back up to the set point.

Back pressure regulators are commonly used in process control applications to maintain a consistent pressure in pipelines and process units. They are used in a variety of industries including chemical, petrochemical, and power generation. They can help maintain safety, improve process efficiency and productivity, and help prevent equipment damage.

What is Refractometer Critical Angle Measurement?

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. 


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.

The use of an upstream valve has many disadvantages. This design requires high pressure making it sub-optimal for critical low-pressure gases and low full-scale flow rate. It also means matching the two individual pressure transducers perfectly. 

Brooks Instrument designed a patented integrated differential pressure transducer, GP200 P-MFC, to address the disadvantages. The GP200 has one actual differential transducer instead of two, eliminating the need to match the two individual pressure transducers, significantly reducing measurement uncertainty, and improving accuracy, particularly for critical low vapor pressure process gases. Its downstream valve architecture will operate at much lower inlet pressures and across a broader range of pressures. The downstream valve also minimizes the bleed-down effect and ensures that the device is insensitive to dynamic outlet conditions.

The GP200 Series P-MFC features a patented architecture that overcomes the limitations of conventional P-MFCs to provide the most precise process gas delivery even when delivering low vapor pressure process gases. It includes several unique design aspects, including an integrated differential pressure sensor coupled with a downstream valve architecture enabling the most precise process gas delivery over the industry's broadest range of operating conditions.

Since GP200 Series supports a broad range of process conditions, it can be used as a drop-in replacement and upgrade for many traditional P-MFCs and thermal MFCs. It reduces the complexity and cost of ownership of the gas delivery system because it eliminates the need for components such as pressure regulators and transducers.

GP200 FEATURES

  • True differential pressure measurement
  • Lower inlet pressure operation
  • Downstream valve architecture
  • Matched transient response
  • Zero Leak-by Control Valve
  • MultiFlo™ technology offers unparalleled flexibility—one device can be programmed for thousands of different gas and flow range configurations without removing the MFC from the gas line or compromising accuracy
  • Local display indicates flow, temperature, pressure and network address
  • DeviceNet™, EtherCAT®, RS-485 L-Protocol and analog interfaces

GP200 BENEFITS

  • By removing the requirement to match and compensate two separate pressure transducers, the GP200 differential pressure technology reduces measurement uncertainty for enhanced accuracy, repeatability and drift performance.
  • Safer fab operation at lower inlet pressures is now achievable with a P-MFC due to the GP200 differential pressure sensor that is specifically optimized for low differential pressure measurement.
  • The downstream valve architecture ensures accuracy is independent of downstream pressure, enabling flow delivery into pressures as high as 1200 Torr. The fast closing valve addresses non-productive recipe wait times, or "tail effects," seen in upstream MFC valve designs that require additional time to bleed down their internal volume of gas.
  • Ultra-fast, highly repeatable ascending and descending flow stabilization time enables tighter process control in advanced high cycle Deposition and Etch processes.
  • 100X improvement in valve shut-down
  • With MultiFlo™, MFC full scale flow range can be re-scaled down typically by a factor of 3:1 with no impact on accuracy, turndown or leak by specifications, for optimum process and inventory flexibility 
  • Convenient user display and independent diagnostic/service port aids device installation, monitoring and troubleshooting
