The PFS WM Series Liquid Wafer-Style Turbine Flow Meter provides accurate and reliable liquid flow metering for industrial applications. This liquid turbine flow meter fits between customer-specified flanges, which helps simplify installation in compatible piping systems.
The WM Series offers strong performance across a wide flow range. It provides ±1.0% linearity over the flow range for most models, with ±0.1% repeatability. The WM0038 model provides ±2.0% accuracy and ±0.1% repeatability. In addition, the standard operating temperature range runs from -100°F to +300°F. A special coil option extends service up to 850°F.
The WM Series uses durable materials for demanding liquid service. The meter body and rotor supports use 316 stainless steel. The rotor uses CD4MCu / 416 stainless steel, while the shaft and bearings use tungsten carbide.
Available through Westech Industrial Canada Wide, the PFS WM Series can support liquid flow measurement projects that require product selection, technical support, service coordination, and replacement planning. Westech can also support custom fabrication needs when projects require integrated panels, packaged assemblies, or other project-specific solutions around the flow measurement system.

Description
Accurate Liquid Flow Measurement
The PFS WM Series helps operators measure liquid flow with dependable turbine meter performance. Most models provide ±1.0% linearity over the flow range. They also provide ±0.1% repeatability, which supports consistent readings over repeated operation. As a result, this liquid turbine flow meter suits applications where stable measurement matters.
The WM0038 model uses a different accuracy rating. It provides ±2.0% accuracy and ±0.1% repeatability. Therefore, users should confirm the correct model before selection. Westech Industrial can help review the flow range, connection size, and accuracy requirements for Alberta applications.
Wafer-Style Installation Between Flanges
The WM Series uses a wafer-style design that installs between customer-specified flanges. This configuration gives project teams flexibility when matching the meter to existing pipe and flange requirements. It also supports applications where a compact turbine meter body helps with installation planning.
Because the product range includes multiple end connection sizes, teams can select a model that matches the required flow rate. The series starts at 3/8” connection sizes and extends up to 10” connection sizes. In addition, the flow ranges cover small liquid flow rates and larger industrial flow rates.
Built with Durable Meter Materials
The WM liquid turbine flow meter uses materials selected for industrial liquid flow service. The meter body uses 316 stainless steel, and the rotor supports also use 316 stainless steel. The meter rotor uses CD4MCu / 416 stainless steel. Additionally, the rotor shaft and bearings use tungsten carbide.
These materials help the meter maintain performance in demanding environments. They also support longer service life when the application matches the meter specifications. For this reason, proper product selection remains important. Westech can help customers review process conditions before ordering.
High Pressure and Wide Temperature Capability
The WM Series supports maximum pressure up to 6,170 PSI. It also handles a standard operating temperature range from -100°F to +300°F. For higher temperature applications, a special coil option extends the capability to 850°F.
This broad operating window helps the WM Series support a range of liquid metering requirements. However, pressure, temperature, connection size, and flow range should always align with the selected model.
Magnetic Pickup, Retrofit Kits, and Service Support
A magnetic pickup comes standard on all models at no extra charge. This supports electronic flow signal requirements without adding a separate pickup option.
The WM Series also supports long-term maintenance planning. A full line of retrofit kits is available, and factory refurbishment is available. Repair kits include two rotor supports, one rotor, and two retaining rings or replacement screws. Additionally, calibration and recertification support can help keep flow meters aligned with operational requirements.
