GENERAL DESCRIPTION:
Sure Flow Products variable area flow rate indicators are designed for touch industrial applications.This flow indicator is mechanical with a spring-loaded vane and pointer indicator. This allows for mounting in any orientation and is ideal for use with dark or opaque fluids. The body mounts between flanges which reduces weight, size and cost. Standard with mechanical indication with options of one or two switches, and /or a two wire 4-20mA output signal.
