Metering substances: water /oil Please indicate your metering substances with your order. Technical parameters: Storage temperature: -29°C 82°C Media temperature range: -20°C 93°C Max. static pressure: 16bar, 30bar custom-made Average pressure loss: 0.01bar Output: one SPDT dry contact output, one or two for optional Switch: 5A(max),250VAC /DC Electrical connection: DIN 43650 (105°C 2×0.75 or 3×0.75mm for optional) Protection class: IP54 WFS16 differential pressure flow switch with single set point is specially designed to monitor flow of heat exchanger. It is a new type, when the water flow (different pressure) in system rises up or falls down to one set value, it will output a warning or sent switch-off signal to automatic control system. WFS16 series is a kind of flow switch with single set point and it could not be changed. So if the Air-Conditioner producers choose this type, the user could not change the flow set point, then it will avoid the mistake in Installing Air-Conditioner. It is usually used to monitor the flow in plat and double pipe heat exchanger, installed in the water outlet. The manufacturer printed the calibrated value on the label of product, does not readjust in the field, could calibrate by professional instrument according to the differential pressure that required by equipment.
