PFS SLGM Slim Line Gas Flow Meter

The PFS SLGM Slim Line Gas Flow Meter provides accurate and reliable gas flow measurement in a compact wafer-style design. It suits industrial applications that need dependable turbine meter performance without a large meter body.

This slim line gas meter measures flow rates from 0.5 to 250 ACFM across the available model range. It also offers strong repeatability, stainless steel construction, and NIST traceable calibration. In addition, its CRN certification supports use in Canadian industrial applications.

Westech Industrial offers the PFS SLGM Slim Line Gas Flow Meter Canada wide. Our team can help customers review flow range, connection requirements, service needs, and system compatibility. Westech also supports projects with service capabilities and custom fabrication when the meter must fit into a larger process package or measurement system.

Description

Compact Wafer-Style Design

The PFS SLGM Slim Line Gas Flow Meter uses a wafer-style connection. This design helps reduce space requirements compared with larger meter assemblies. As a result, it can work well in gas measurement applications where space matters. The slim body also supports straightforward installation into compatible process piping.

Accurate Gas Flow Measurement

The SLGM gas flow meter delivers linearity of +/- 1.0% over its standard flow range. The linear range depends on gas density, so proper model selection matters. The meter also offers repeatability of +/- 0.1% over the standard flow range. Together, these performance values help operators measure gas flow with confidence.

Broad Flow Range Options

The SLGM Series covers 0.5 to 250 ACFM across the available models. Customers can choose from 1” and 2” meter sizes. This flexibility helps match the slim line gas meter to the required flow profile. Available models include low, standard, and high-range options for different operating needs.

Stainless Steel Construction

The meter body uses 316 stainless steel, while the rotor uses 17-4PH stainless steel. The bearing assembly uses 440C stainless steel ball bearings with a self-lubricating retainer. These materials support reliable operation in demanding industrial environments. Other material options may also be available through consultation.

Wide Temperature and Pressure Capability

The PFS SLGM Slim Line Gas Flow Meter handles temperatures from -450°F to +450°F. A special coil option extends the temperature capability to 850°F. The meter also supports operating pressures up to 3,700 psig, subject to the process piping capacity. This range gives customers more flexibility for industrial gas applications.

Included Magnetic Pickup Coils

Each turbine meter includes magnetic pickup coils at no extra charge. These coils help support signal output from the meter. The SLGM Series can also pair with monitors or interface modules to create a more complete gas flow measurement system.

Retrofit and Refurbishment Support

The SLGM Series includes a full line of retrofit kits. Factory refurbishment is also available. This helps extend service life and supports replacement projects where existing equipment needs an upgrade or refresh.

Applications

The PFS SLGM Slim Line Gas Flow Meter suits gas measurement applications that need accuracy, compact installation, and stainless steel construction. It also works well when customers need model options across different ACFM ranges.
