The F195 has been developed for the valve position indication and monitoring in hydraulic systems. By using a bi-directional flow meter to measure the volume displaced by the actuator, an accurate position of the system is calculated.
The display shows the position as a percentage as well as with the text “open” and “closed” for the minimum and maximum positions. As standard, the analog output mirrors the percentage displayed which can be used to transmit the valve position. The usual difficulties encountered in such applications include: very low flows, vibration, and thermal expansion of the oil and high ambient temperatures.
