Multivariable Vortex Flowmeter
The Pro-V™ Model M23-V insertion vortex shedding flowmeters deliver a direct reading of volumetric flow rate, making it generally the most cost-effective solution for liquid flow monitoring. Great for use in applications ranging from general water flow measurement to hydrocarbon fuel flow measurement.
Vortek Instruments Pro-V multivariable flowmeters utilise three primary sensing elements
- a vortex-shedding velocity sensor
- an RTD temperature sensor and
- a solid-state pressure transducer - to measure the mass flow rate of gases, liquid, and steam.
Systems that use external process measurements to calculate mass flow may not provide adequate compensation for the fact that process conditions 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 Pro-V multivariable 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 maintenance costs. The product line is available with a wide range of options and meter configurations to meet your specific application requirements.
Accuracy - Mass flow rate accuracy for gas and steam based on 50-100% of the pressure range.

Principle of Operation
Insertion vortex flowmeters measure flow by detecting the local velocity at a strategically located position within the pipe. The Pro-V™M23 detects the frequency at which vortices are alternately shed from the bluff body located within the sensor head. The Pro-V™M23 uses the local velocity, along with other parameters, such as fluid type, pipe size, and Reynolds number to calculate the average pipe velocity, and consequently, the volumetric flow rate.
The Model M23-VTP offers you flow computer functionality in a compact field device. This multivariable instrument incorporates temperature and pressure sensors to provide an instantaneous reading of the compensated mass flow rate of gases, liquids, and steam. In addition to outputs for totalized mass and alarm settings, the field-configurable electronics deliver up to three analog 4-20 mA outputs of five process measurements, including volumetric flow rate, mass flow rate, pressure, temperature, and density.
Pro-V™ Model M23-VT
The Model M23-VT integrates a precision 1000 Ohm platinum RTD temperature sensor that can be used to calculate and output a compensated mass reading. This device is typically used to measure the flow rates of saturated steam.
Pro-V™ Model M23-V
The Model M23-V delivers a direct reading of volumetric flow rate–-generally the most cost-effective solution for liquid flow monitoring–in applications ranging from general water flows to hydrocarbon fuel flow measurement.
Pro-V™ Model M23-EM
The Model M23 Energy Monitoring option permits real-time calculation of energy consumption for a facility or process. The meter can be programmed to measure steam, hot water, or chilled water. The Model M23-VTP flowmeter monitors one side of the process, either sent or returned, and uses the input from a second separate temperature sensor on the opposite leg of the process to calculate the change in energy. Selectable energy units include Btu, joules, calories, Watt-hours, Megawatt-hours, and Horsepower-hours. The local or remote electronics indicate two temperatures, delta T, mass total, and energy total.
Pro-V™ Model M23-VTEP, VETEP
Similar to M23-VTP but with the option for external input (T or P) via RTD
or 4-20mA or one of each.
