LFE, Digital Liquid Flow Sensor, Electromagnetic, 2-Screen 3-Color Display, IP65, 0.5-200 Lpm
LFE is a digital flow sensor for water and non-corrosive conductive liquids. While the PF3W sensors detect flow using the Karman vortex principle, LFE applies Faraday's law of induction. There are no obstacles or moving parts in the flow path, yielding a smaller pressure loss which saves pumping energy. Detectable liquids have fewer viscosity restraints. Finally, the flow direction can be changed after installation. The 2-screen, 3-color display can show the measured value in the primary screen, while viewing a variey of secondary data in the sub-screen. Two outputs are available, including two switch signals, or a switch and analog signal. Options include a mounting bracket and M12 lead wire. Piping connections are C37 brass as standard, while the -X8 option offers 304 stainless steel. LFE is IP65 rated, and CE and RoHS compliant.

PF3W7-Z, Digital Water Flow Sensor, Lightweight, 2-Screen 3-Color Display, IP65, 0.5-100 Lpm
Series PF3W7-Z digital flow sensor constantly monitors water or coolant flow. All "Z" models have redesigned piping adapters, imparting a 13-53% weight reduction depending on flow range. PF3W7 features an integrated 3-color, 2-screen display. Options include a manual flow adjustment valve and temperature sensor. The instantaneous flow value can be displayed on the main screen, while temperature can be monitored on the subscreen. Change color from green to red or vice versa to indicate a flow set point has been reached. The white subscreen can also show the set point, accumulated or peak/bottom value, or a line name instead of the temperature. The display rotates in both clockwise and counter-clockwise directions, offering improved readability during operation. Switch and analog voltage or current signal outputs can be read over the M8 cable. PF3W7-Z is IP65 rated, and is both RoHS and CE compliant.
