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 ttings,

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.
