GENERAL INFORMATION
This unique system of 2" to 8" turbine meters uses just
one moving part, a precision helical rotor. Rotation of
the rotor is electronically detected and processed. The
high-quality jewel bearings and shafts minimize friction
while providing long wear life in non-lubricating fluids.
The entire rotor assembly can be easily removed for
field service without removing the meter from the pipe.
WTP bodies are fabricated from Schedule 80 PVC fittings,
WTC bodies from carbon steel tubing, and WTS bodies from
stainless steel tubing. The turbine insert on WTC and WTS
meters is machined from a stainless steel casting. The WTP
turbine insert is machined from a solid piece of PVC. Turbine
rotors on all models are Kynar (PVDF).
WT meters can be ordered with various output options.
The basic model (100) comes with pulse output only. An
electronic display (Seametrics FT420) is mounted on the
101 model to display flow rate and total (resettable or
non-resettable), and provide a programmable pulse or
4-20 mA output. Other electronics options include a blind
4-20 mA transmitter (AO55) on the 102 model and a
battery-powered (FT415) rate/totalizer plus pulse output
for applications that lack power (104 model). All of these
controls/displays can be mounted on the meter or remotely
mounted on a wall or panel up to 2,000 feet away. WT-
Series meters are compatible for use with most other
remote-mount Seametrics displays and controls as well.
