Piston flow switch HD series

for liquidsstainless steelIP65

High switching power Compact design This flow switch introduces, as regards the detection of the flow rate through the floating piston system, a series of improvements that increase the reliability. In the HD2F version the flow chamber and the sensing element have been redesigned to obtain a better stability to changes in viscosity and a greater insensitivity to possible impurities of the fluid. The new calibration system, with safety lock, allows accurate adjustment of the set value. The electrical connection is made via DIN 43650 plug and PG9 cable gland. In addition, a series of options of indication instruments, in fact, make it a versatile flow meter able to satisfy the most different requirements. The display of the flow rate is on a magnetic coupled dry scale with analog indication in % or l / min. ● Hermetic separation between flow chamber and electric head. ● No restrictions on mounting position. ● High operating pressure and temperature. ● Calibration adjustment. ● Indication of the flow rate on a dry scale, on request ● Builtin thermometer, on request.
