GENERAL INFORMATION

WT-SERIES INSTRUCTIONS

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 uids. The entire rotor assembly can be easily
removed for eld service without removing the meter from the

pipe.

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 ow 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

WTP bodies are fabricated from Schedule 80 PVC ttings 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

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.

rotors on all models are Kynar (PVDF).

WT-SERIES INSTRUCTIONS

Installation

CAUTION: These water meters are not

recommended for installation downstream of
the boiler feedwater pump where installation
fault may expose the meter to boiler pressure
and temperature. Maximum recommended

temperature is 120˚ (PVC) or 200˚ (Metal).

Piping Conditions. Installing the meter with 10 diameters
of straight pipe upstream and 5 downstream is
recommended.

Flanges. For WTS meters, standard anges are 150 lb. ANSI
drilling. PVC meters can be installed with optional anges

according to pipe manufacturer’s recommendations. For

PVC a bolt torque of 20-30 ft-lb for 3” and 4” anges, and
35-50 ft-lb for 6” anges is recommended.

Maintenance and Repair

Recalibration. If it is necessary to recalibrate the meter for

any reason, this can be done by any Seametrics-authorized
facility. Call your supplier for information.

Either partial or full-face gaskets can be used. Tighten the
bolts evenly. Use care to prevent a misaligned gasket from

entering the ow stream.

Position. The WT-Series are all-position meters, operable
in a vertical or horizontal position, with the meter insert
in any radial position. A horizontal position is preferred if
there is a risk of air becoming trapped due to constant low

ows. Operating the meter in partially-lled pipe will result

in inaccuracies.

Turbine Insert Removal and Installation.
CAUTION: First remove all pressure from the line. Then

remove the screws or bolts that hold the insert in place and
tug gently until the insert comes free. A twisting motion
can help to loosen the O-ring seal. Reverse the procedure
to reinstall, after coating the O-ring with lubricant (plastic
compatible in the WTP). Do not overtighten.

Rotor and Shaft Replacement. Examine the rotor to
determine if bearings or shaft are damaged or excessively
worn. The rotor should spin smoothly and freely, with
no visible wobble. Back and forth play should be very
minor, less than 1/64”. If it is necessary to replace the

rotor or shafts, rst back out both shafts with a small

blade screwdriver. The rotor will come free as soon as the
shaft ends come free of the rotor bearings. Reverse the
procedure to reinstall. Note: Do not overtighten the shaft
screws. Check to be sure that a small amount of free play
between the shaft ends and the bearings remains.

Sensor Replacement. This is rarely necessary. However,
certain electrical conditions can damage the sensor. To

replace it, rst remove the electronics module. Disconnect

the sensor leads from the electronics module terminals and
remove the threaded plug over the sensor. Finally, remove
the sensor by pulling on the sensor leads. A gentle tug

should be sufcient. Reverse the process to replace the

sensor.
