Paddle flow meter PWM series

volumefor liquidsvertical

PWM paddle-wheel flowmeter for liquid flow measurement. Design Features Flow meters for liquid flow applications Jewel bearings allow for very low minimum flow rates Easy to install and operate Mounted horizontally or vertically Only one moving part Flow indication via transparent acrylic cover Versatile square wave signal Female NPT ports Multiparameter: Flow and temperature outputs. Platinum RTD option Polypropylene and chemically resistant PVDF models Description Principles of Operation Fluid flowing through the unit causes the paddle wheel to spin. As the magnets embedded in the paddle spin past the sensor, electrical pulses are produced in which frequency is proportional to the flow rate. The revolutions per minute and the K-factor (number of pulses/Gallon) make it is possible to calculate the flow volume passing through the unit. SPECIFICATIONS OUTPUT SIGNAL - NPN open collector (load 30 mA max) DIMENSIONS - 56H x 108L x 53D mm (2.2 x 4.25 x 2.2")Without RTD and Hall switch adapters. CABLE - 1.8 m (6') or 3.7m (12') optional RTD - Platinum 0.00385 TCR, meetsEN 60751, Class B
