The complete lack of moving parts of this insertion flow sensor is the source of its reliability. There is no rotor to stop turning in dirty water and there are no bearings to wear out. Brass and stainless steel models withstand a variety of temperature, pressure, and chemical conditions. Reverse flow output and immersibility are optional. A rapidly reversing magnetic field is produced in the lower housing. As the fluid moves through this field, a voltage is generated that is measured and translated into a frequency signal proportional to flow rate. This square wave signal can be sent directly to a PLC, control or converted to 4 to 20 mA with the FTB700-T shown below (optional). A modular system of electronics can be attached directly to the flow sensor or remotely mounted. The FMG900 series can provide full indication of rate and total with the (optional) FTB700-D or just a 4 to 20 mA output with the (optional) FTB700-T blind transmitter. The adaptor fitting of the standard unit is a male NPT, and can be directly threaded into ordinary saddles or threaded weld fittings. The hot tap versions include an isolation valve, allowing hot-tap installation, or installation and removal under pressure. Hot tap units include the appropriate installation valve.
