Spirax Sarco's TVA Target Variable Area flowmeter is available in DN50, DN80 and DN100 sizes
Spirax Sarco's TVA Target Variable Area flowmeter is available in DN50, DN80 and DN100 sizes. A built-in temperature sensor is designed to provide full density compensation and enable 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.
Communication with different host systems is possible with a choice of Digital ModBus, 4-20mA and pulse outputs. The TVA is supplied as a fully calibrated unit. The design of a variable area cone in flow path is engineered to make the flowmeter resistant to erosion from water droplets in saturated steam. It has a wafer construction and requires only six diameters of straight pipe upstream and three downstream.
