Flow-Mon flow monitors and flow switches
Flowmon continues to be a standard selection for lubrication and cooling systems. In addition to the standard calibrated scale/pointer flow rate indication with low flow switching, the unit is available with the I-Mon analogue output. The simple circuitry gives 4-20mA from a 2 wire closed-loop powered by 12-24 vDC. This design is a sensitive frictionless current pick-up using the direct relative radial position of the shaft to the PCB to produce the current range scaled to the calibrated rate of flow through the meter. The spring loaded vane in the body of the unit gives a flow reading relative to the variable opening produced by the applied pressure drop. A valuable tool for any automatically controlled process system. Repeatability <0.2%.
