Understanding the Operation of Mass Flow Controllers (MFCs)
The basic construction of mass flow controllers (MFCs) consists of four main components. A body, a thermal sensor, a printed circuit board, and a magnetic control valve. As gas enters the flow body, a laminar flow element or restrictor diverts a precise portion of the gas to pass through the thermal sensor. The thermal sensor is the heart of the mass flow controller and consists of a bypass tube fitted with a heater element and two temperature sensors. As gas enters the sensor bypass tube, the upstream and downstream temperature sensors measure the temperature differential between gas entering the bypass tube and exiting it.
When choosing an MFC supplier, consider whether the manufacturer provides zero stability specifications, also known as sensor stability, which indicates the device's ability to maintain accuracy over time. Good sensor stability ensures the MFC delivers highly accurate and consistent results with less frequent recalibration or replacements needed. A stable, precise sensor guarantees regular, precise process control. As the thermal sensor measures the change in the flow temperature, it sends a signal to the circuit board, which interprets the data into flow output and compares it to the setpoint received from the user setpoint signal. If the setpoint, or required value, is higher than the measured value or flow output, the controller will open the control valve, letting more flow through. Suppose the setpoint is lower than the flow output. In that case, the control valve will close, decreasing flow, caused when a coil inside the magnetic control valve sends an electrical current around a valve stem, which moves the valve plunger by thousands of an inch. The circuit board is the device's brain, so pay close attention to the electronics and firmware architecture when evaluating an MFC. The MFC should have the ability to support advanced alarms and diagnostics to monitor and correct issues before the overall process is negatively affected. Check to see what built-in alarms and diagnostics are available.
Brooks Instrument devices support flow output and additional alerts like flow totalization, valve drive, flow obstruction, and calibration. All Brooks devices are tested as complete systems to ensure robust and accurate operation and maintain calibration to international standards.

Critical Ethylene Level and Flow Application Brochure
In ethylene plants, balancing environment, health, and safety is essential while maximizing productivity.
Level and flow instrumentation will assist in preventing loss of primary containment and maintaining a safe environment inside of the tank. That’s critical, because incident consequences are significant, with the direct cost of a work-related death of $1M and indirect costs approximately 4 times greater. In addition, there is the lasting damage to your brand reputation and the compromised safety of the local community. Instrumentation can also assist in maximizing productivity, including interface type measurement in some of the harshest environments.
This brochure contains a wide spectrum of Magnetrol® and Orion Instruments® level and flow products that conform to the latest safety standards, including SIL requirements, to assist in the most critical applications in ethylene plants.

Sliding Gate Control Valves from Schubert & Salzer
Schubert & Salzer's sliding gate control valves are designed as an effective alternative to traditional control valves. The sliding gate valve controls liquid, vapor, and gaseous media precisely, quickly, and economically. The design is uniquely simple, but is intelligently built to handle complex applications that require precise control under taxing conditions. They are an excellent choice for a variety of media, including steam, liquids, and gases.
Sliding Gate Control Valve Operation
A sealing plate with many crossways slots of equal height is fixed in the body at right angles to the flow direction. A moving disc with the same slot arrangement moves in parallel to the fixed disc, thereby changing the flow cross-section. The prevailing differential pressure presses the moving disc against the fixed disc and seals it.
The machined orifices in the fixed plate or disc can vary in design, size, and configuration, determining the flow coefficient (Cv) and the flow characteristic of the valve. As the cross sectional area changes and the valve modulates, flow is broken apart, creating a variable field of area flow, which reduces energy and noise. The differential pressure creates a unique seal between the two plates, and when in the sealed position, an overlap of approximately 1 mm creates a leak-tight valve.
ADVANTAGES OF THE SLIDING GATE CONTROL VALVE
- Fits into tight spaces
- Outstanding rangeability
- 40:1 to 160:1
- Easy to install and maintain
- Variable Cv Values
- Significantly reduced energy consumption
- Minimal wear
- Extremely low leakage rate
- Optimal flow control
- Maximum differential pressures
