PMT Available Options

The cast iron Lo-Loss® is designed to measure the flow of gases, water, wastewater, sludge, and slurry flows in full pipes. The iron Lo-Loss® design is furnished in four models, depending on the application.

Model PMT is a flanged cast iron Lo-Loss® meter designed for liquid and gas flow measurement. Available throat materials are bronze and stainless steel. All valves, except butterfly valves, may be direct-coupled downstream for control purposes without loss of accuracy. The Lo-Loss® can be supplied with flanges, mechanical joints, or plain ends. Typical throat materials are bronze and stainless steel.

Model PMT-C is a flanged cast iron primary element designed to utilize a direct-coupled butterfly valve in a rate-of-flow controller for liquid or gas service. The direct-coupling of the butterfly valve will not affect the discharge coefficient of the primary element. The meter outlet can be modified to accommodate a valve one or more line sizes smaller than the main piping run.

Model PMT-S is a flanged primary element designed for wastewater, sludge, slurry, or other fluids with suspend-ed solids. Manual vent cleaners are provided as standard; automatic vent cleaners orasealed diaphragm system are available as options. An inspection port andwater purge systems, either continuous or timed, are also available. Model PMT-SC is a rate-of-flow controller designed for use in applications where the line fluid contains sus-pended solids. The primary element is provided with vent cleaners or a purge system and will accept a butterfly valve bolted directly to the downstream flange. This allows the

PMT-SC to be used in many applications where other standard venturi or flow tubes cannot be used.
