BVT Available Options

The cast iron Wyatt Venturi Tube is available in four styles for specific applications.

Model BVT is a flanged cast iron primary element designed for liquid and gas flow measurement. Typical throat materials are bronze and stainless steel. All valves, except butterfly valves, may be direct-coupled down-stream for control purposes without loss of accuracy. The BVT can be supplied with flanges, mechanical joints, or plain ends. Typical throat materi-als are bronze or stainless steel.

Model BVT-C is a flanged cast iron primary element designed to utilize a butterfly valve for rate-of-flow control in liquid or gas service. The Wyatt Venturi tube is constructed to accept a butterfly valve bolted directly to the downstream flange allowing the BVT-C to be utilized as a rate-of-flow controller. The butterfly valve does not affect the accuracy of the primary element. The meter out-let can be modified to accommodate a valve one or more line sizes smaller than the main piping run.

Model BVT-S is a flanged primary element designed for wastewater, sludge, slurry, or other fluids with sus-pended solids. Static pressure taps assure stable measure-ment and minimize solids buildup at the tap. Manual vent cleaners are provided as a standard; automatic vent cleaners or a sealed diaphragm system are available as options. An inspection port and water purge systems, either continuous or timed, are also available.

Model BVT-SC is for rate-of-flow controllers used in applications where the line fluid contains suspended solids. The primary element is provided with vent cleaners, sealed diaphragms, or a purge system, and will accept a butterfly valve bolted directly to the downstream flange. This allows the BVT-SC to be used in many applications where other standard venturi or flow tubes cannot be used.
