A pressure controller combines pressure measurement with a regulating valve to maintain a target gas-path pressure. The host provides a pressure command, the controller adjusts valve operation, and a pressure reading can be returned to the host.
Control interfaces vary by manufacturer and model. Analog voltage/current signals or digital communication may be available, but a historical general interface example does not define the options for current Flowmethod products.
Before ordering, confirm the power supply, control signal, pressure range, required accuracy, gas compatibility and environmental/protection requirements. Pressure control and mass flow control serve different objectives and must not be treated as interchangeable.

Flowmethod designs, develops, manufactures and supports gas mass flow controllers, meters and custom gas-control and mixing systems. Configurations are matched to the customer's process and operating requirements.
