Information about Flow Controllers

Flow controllers monitor and maintain proper humidity levels in environmental test applications, or in other areas such as food storage or electronic room regulation. They can have three main ways of controlling low: limit control, linear control and advanced or nonlinear control. Limit control interrupts power through the load circuit when flow exceeds or falls below the limit set point. A limit controller can protect equipment and people when it is correctly installed with its own power supply, power lines, switch and sensor. Advanced or nonlinear control uses process control strategies beyond PID loop control, such as dead-time compensation, lead/lag, adaptive gain, neural networks, and fuzzy logic. Common functionalities for flow controllers are rate indication and control as well as batch or totalizer indication and control.

Products & Services Related to Flow Controllers

Batch Controllers

Batch controllers maintain the correct size of a discrete batch of process material, such as the volume of a liquid. They are often interfaced with sensors such as load cells, or with volumetric flow meters.

Humidity Controllers

Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms.

Level Controllers

Level controllers monitor, regulate, and control liquid or solid levels in a process.

pH Controllers

pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application.

Pressure Controllers

Pressure controllers accept input from pressure sensors, transmitters, gauges, and other devices and subsequently control adjustment to the pressure to maintain or achieve the desired pressure level.

Universal Process Controllers

Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.

Web Controllers

Web controllers maintain control functionality over processes with web or sheet rollers. Control functionality includes maintaining tension of the web, centering on the track, and material feed rates.
