PFS WMG Series Gas Flow Meter

The PFS WMG Series Gas Flow Meter provides accurate and reliable gas flow measurement for industrial applications across Canada. This wafer-style turbine gas flow meter supports flow rates from 0.5 to 1,250 ACFM. It also handles operating temperatures from -450°F to +450°F. With a special coil, it can support temperatures up to 850°F.

The WMG Series combines stainless steel construction with strong repeatability and linear performance over its designed operating range. Each turbine meter includes magnetic pickup coils at no extra charge. In addition, users can pair the WMG Series with monitors or interface modules to create a complete flow measurement system.

Westech Industrial supplies the PFS WMG Series Gas Flow Meter Canada wide. Our team can support product selection, service requirements, calibration planning, and replacement needs. When your application needs more than a meter, Westech can also help with custom fabrication. This includes integration into panels, assemblies, shelters, or application-specific measurement packages.

Description

Accurate Gas Flow Measurement

The PFS WMG Series Gas Flow Meter supports accurate gas flow measurement across its designed operating range. It offers linearity of ±1.0%, depending on gas density. It also provides repeatability of ±0.1% over the flow range. As a result, operators can count on stable measurement performance in demanding gas applications.

Wide Flow Range

The WMG Series covers a broad flow range from 0.5 to 1,250 ACFM. This makes the series suitable for multiple pipe sizes and flow demands. The model range includes 1”, 2”, 3”, and 4” options. Therefore, users can match the meter to the process instead of forcing one size across different applications.

Rugged Stainless Steel Construction

The WMG Series uses durable stainless steel materials for key components. The meter body uses 316 stainless steel, while the rotor uses 17-4PH stainless steel. In addition, the bearings use 440C stainless steel ball bearings with a self-lubricating retainer. This construction helps the meter perform in tough industrial gas measurement environments.

Broad Temperature Capability

This gas flow meter handles a wide standard temperature range from -450°F to +450°F. For higher-temperature applications, a special coil can extend capability up to 850°F. This flexibility helps users address demanding temperature conditions while maintaining consistent gas flow monitoring.

Wafer-Style Connections

The WMG Series uses wafer-style connections for installation between flanges. This compact connection style helps simplify installation in many industrial piping systems. It also supports a streamlined meter design where space matters.

Retrofit Kit Availability

A full line of economical retrofit kits supports the WMG Series. This helps users replace or upgrade existing meter installations with less disruption. Retrofit options also make the series useful for maintenance planning and long-term equipment support.

System Integration Options

The WMG Series can work with monitors and interface modules to create a comprehensive measurement system. This allows users to build a setup that fits their signal, display, and control needs. Westech can also support integrated solutions through service coordination and custom fabrication.

Certified and Traceable Performance

The WMG Series carries CRN certification and includes NIST traceable calibration. These certifications support confidence in regulated industrial environments. They also help users meet internal quality, documentation, and compliance needs.

Applications

The PFS WMG Series Gas Flow Meter suits applications that need reliable turbine gas flow measurement, broad temperature capability, and stainless steel construction.
