Liquid flow switch 1900

reedhigh-temperaturereed switch

Standard flow calibration is in water @ 70°F with lead wires up. Calibrated on increasing flow. Temperature effect on flow settings: water calibration, slight change; oil varies with viscosity. Set point accuracy will change slightly in other than calibrated position. Optional aluminum housings with SST trim are stocked. Consult factory. Optional mounting holes available. Consult factory. Also available: leads in different lengths, cable, terminated ends, etc. Consult factory. Relays for higher loads are available. See accessories section for details High-temperature units available to 400°F. Consult factory. Standard flow settings are calibrated in water. Other set points in water or oil are available. Consult factory. Other wetted materials: Hysol Epoxy All SST piston for either brass or SST housing, eliminating hysol epoxy. Consult factory. Calibration: Flow stands are calibrated to the National Bureau of Standards and Thomas Products Ltd. recalibration schedule.
