Description

High Accuracy Flow Measurement

The PFS WHA Series gives customers a dependable wafer turbine flow meter for accurate industrial flow measurement. It provides +/- 0.5% linearity over the standard flow range. It also delivers +/- 0.1% repeatability, which helps operators track flow performance with confidence. For demanding applications, premium accuracy options may also be available by consultation.

Broad Operating Range

The WHA Series supports a wide range of operating conditions. It handles flow rates from 4 to 1,250 gpm across listed meter sizes. In addition, it supports operating pressures up to 6,170 PSI. The meter also works across temperatures from -450°F to +450°F. With a special coil, it can support temperatures up to 850°F. As a result, the WHA Series suits many demanding industrial environments.

Wafer-Style Connection

This high accuracy wafer meter installs between customer-specified flanges. Therefore, it works well where teams need a compact flow measurement solution for flanged piping. The wafer-style configuration also supports clean integration into new systems or retrofit projects. Additionally, Westech can help customers review flange requirements during product selection.

Durable Material Options

The WHA Series uses 316 stainless steel for the meter body as standard. Rotor material options include 17-4PH, Nickel 200, and Duplex stainless steel. Bearing options include 440C stainless steel, hybrid ceramic ball bearings, and hard carbon composite. Additional materials may also be available by consultation. Therefore, customers can review compatibility needs before choosing the final configuration.

Pickup Coils and System Integration

Magnetic pickup coils come included with the WHA Series. The meter can also work with monitors or interface modules to create a more complete flow measurement system. This helps teams bring turbine meter data into their operating workflow. Moreover, Westech Industrial can support integration planning for Alberta customers who need the meter as part of a larger process solution.

Calibration, Retrofit, and Refurbishment Support

The WHA Series includes NIST traceable calibration and CRN certification. A full line of calibrated retrofit kits is available. Factory refurbishment is also available. In addition, complete support and recertification services can help extend the life of existing flow meters. Westech can assist with service coordination, replacement planning, and application support.

Applications

The PFS WHA Series suits industrial flow measurement applications that require accuracy, repeatability, and a compact wafer-style installation. It can support new installations, retrofit projects, and integrated flow measurement systems.
