WT-SERIES INSTRUCTIONS
Seametrics • 253.872.0284 Page 4 seametrics.com
This unique system of 3" 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 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 and
WTS bodies from stainless steel tubing. The turbine insert on
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 FT430/440) can be mounted on the 103 and
109 models 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
(FT450) rate/totalizer plus pulse output for applications that lack
power (107 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 other
remote-mount Seametrics displays and controls as well.
