TVA - Target Variable Area Flowmeter. The TVA is designed for use on saturated steam where there are large variations in flow rates. This is a Control Engineering 2012 Engineers’ Choice finalist.Designed for use on saturated steam, the TVA from Spirax Sarco is available in 2-in., 3-in., and 4-in. sizes. With a wide flow range turndown of 50:1, it is ideal for applications where there are large variations in flow rates. The integral electronics unit removes the need for a differential pressure transmitter, impulse lines, and additional equipment. A built-in temperature sensor provides full density compensation and enables power, energy, flow, total flow, pressure, and temperature to be displayed on the on-board LCD display. All flow parameters are fully configured on an integral keypad so no additional tools or configurations are required for setup and commissioning. Communication with many different host systems is possible with a choice of Digital ModBus, 4 mA to 20 mA and pulse outputs. The TVA is supplied as a fully calibrated unit. The unique design of a variable area cone in flow path makes it highly resistant to erosion from water droplets in saturated steam. As a result, it can be installed for long periods without deterioration in accuracy. It has a wafer construction and requires only six diameters of straight pipe upstream and three downstream, making it suitable for installation in confined spaces.
