Over 40 years of Arjay’s field proven HF capacitance experience has been applied to the 4100-OCF monitor. This unique flow system provides complete flexibility for monitoring a variety of flumes and weirs.
The 4100-OCF sensing probe monitors the capacitance field between the probe and it’s concentric shield within a primary flow device. The Arjay controller converts the water level to flow using the applied Manning equation selected for the flow channel. The 4100-OCF provides a display of flow and totalization. Relays and analog outputs are available for control and interface.

The Arjay PMC (pulse module circuit) installed at the probe converts the separator signals to a frequency pulse. This allows the controller to be safely mounted up to 1 km away from the tank with virtually no loss to signal stability. No operator interface is required at the probe using this unique Arjay PMC design.
All calibration, control interface and power wiring is done at the main control unit. The touch screen provides a simple menu-driven operator interface and display.
The Arjay App board is the heart of the 4100-OCF. This board monitors and controls the signals from the probe, applies the appropriate calibration algorithms and interfaces this information to the touch screen and PLC hardware.
