Flowmeter Controller Interface

A local operator interface (LOI) option is now available on the vendor’s 4800 Series of mass flowmeter controllers.

The LOI provides a 28mm wide by 11mm high back-lit display that securely mounts directly on top of the mass flow instrument and allows the user to power the device via a DC power adapter. The LOI measures the flow signal level from the controllers and displays it on an LCD display. A jog dial button allows the user to send control signals to the device to adjust the flow, perform a valve override, zero the device, and set device configuration parameters. It uses LEDs to provide a visual indication of device status and device mode.
