General

Vortex meters are used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heattransfer oils, boiler feedwater, condensate, etc.

Vortex meters are particularly popular in all sectors of industry for metering steam. Vortex meters measure volume flow, but steam systems are generally rated by mass or energy content, so these meters are frequently used in combination with a pressure and/or temperature sensor and a flow computer. A configuration of this nature helps save energy and is ideal for allocating the costs of generation across multiple consumers.

Transmitters

The transmitter housings are available either intrinsically safe (Ex i) or explosion-proof (Ex d) for hazardous areas, and as compact or remote versions. Both versions of the two-wire transmitter can output volume flow and mass flow.

Prowirl 72


	For standard applications
	Mass flow is computed by entering fixed operating density values or by pressure/temperature-compensated calculation by an external flow computer (e.g. RMS 621 or RMC 621)

Prowirl 73


	Features an integral flow computer for extended functionality
	Direct mass-flow metering of saturated steam with temperature compensation(temperature sensor integrated into the sensor). The saturated-steam curves (IAPWS/ASME) stored in the Prowirl 73 ensure highly accurate measurement in conjunction with simple configuration
	The integral flow computer calculates pressure and temperature-compensated mass flow of gases or superheated steam

Sensors

Safety and dependability in the process and in utility systems require proven and robust sensors that withstand high pressures, temperatures and corrosive fluids. Accuracy: ±0.75% of reading. (liquids); ±1% of reading. (gas/steam).
