Heinrichs DVH Series multivariable vortex flowmeters from KOBOLD Instruments use up to three primary sensing elements for flow measurement: 1.) a vortex-shedding velocity sensor, 2.) an RTD temperature sensor, and 3.) a solid-state pressure transducer to measure the mass flow rate of gases, liquids and steam. Systems that use external process measurements may not provide adequate compensation for process conditions that can change radically between the point of velocity measurement and the point where upstream or downstream pressure and temperature measurements are being made. Because the flowmeter measures all of these parameters in a single location, it delivers a more accurate process measurement. Integrating multivariable output capability with a single line penetration also simplifies system complexity and helps reduce initial equipment cost, installation cost and overall maintenance costs. Three models are available: The DVH-V vortex flowmeter provides a cost-effective volumetric flow monitoring solution for most liquids; the DVH-T vortex flowmeter incorporates temperature sensing to provide a compensated mass flow reading of saturated steam; and the DVH-P multivariable vortex flowmeter delivers mass flow, temperature, pressure and density readings from a single installed device.
