The A-711T output sensor has a VDC output with pulsing for flow totalization and a proportional frequency change for flow rate. For added versatility there are two output choices of 5 VDC or a VDC equal to the input power supplied. The output is compatible with digital rate meters/totalizers and other electronic systems.
• Monitor chilled or hot water flow
• Great for use in monitoring water flow in chillers
• Output package is easily field replaceable
• Weatherproof construction
• UV stablized for outdoor applications
• There are no magnets in the rotor to attract ferrous materials
