Flowrate metering unit - ERVIP–MASS METER

Electronic vortex flow meter-liquid mass and gas volume meter ERVIP–MASS METER

The innovative development is protected by a patent for the invention.


Flowmeters-counters vortex ERVIP–MASSOMETER are designed to measure the volume flow and volume of liquid, mass flow and mass of liquid, density of liquid, volume flow and volume of gaseous media, in relation to which the materials of the flow part in contact with the measured medium (12X18H10T, 14X17H2) are corrosion resistant.

Working media – water, oil, oil emulsion and other liquids, gas (natural, associated, petroleum, compressed air, nitrogen) with parameters:

  • - temperature:
    1. gaseous medium, °C.......................................................................... from minus 40 to plus 70;
    2. low temperature liquid medium, °C...................................................from plus 1 to plus 90;
    3. high temperature liquid medium, °C.............................................. from plus 1 to plus onehundredfifty;
  • overpressure, MPa (kgf/cm2) ...................................................................0 – 4,0 (0 – 40);
  • gas density under normal conditions, kg/m3, not less...................................................0.6;
  • content of mechanical impurities, mg/m3, no more............................................................50;
  • viscosity (for liquids), m2/s, no more.........................................................................12010-6.

Vortex flow meters ERVIP-MASS METER provide the following functions:

  • measurement and calculation of the volume of liquid at r.u. cumulative total, m3;
  • measurement and calculation of the mass of the liquid at r.u. cumulative total, t;
  • measurement and calculation of the volume of gas at r.u. increasing total, m3;
  • measurement and calculation of liquid density, kg/m3;
  • measurement and calculation of the volume flow rate of liquid, m3/h (day);
  • measurement and calculation of the mass flow rate of liquid, t/h (day);
  • measurement and calculation of the volume flow rate of gas, m3/h (day);
  • display of measurement results on the built-in liquid crystal display;
  • transmission of measurement results of volumetric flow and volume of the measured medium in the form of pulse/frequency output electrical signals;
  • protection of installation data from unauthorized access.

Flowmeters-counters vortex IRVIS-MASSOMETER consist of a flow part and an electronic unit.

The flow part is a hollow cylinder, in the cross section of which there is a flow body assembled with a differential type sensing element (sensor).

The electronic unit is connected to the flow part by a tubular bracket. The electronic unit includes a differential signal amplifier, a filter and an output signal generation unit, a liquid crystal indicator. The electronic unit, depending on its configuration, provides signal processing from the sensor and generates pulse/frequency output electrical signals. Additionally, it is possible to display readings on the built-in liquid crystal display.

Flowmeters-counters vortex IRVIS-MASSOMETER have two types of execution: execution 1 and execution 2. Flowmeters of execution 2 are supplied with an additional diffuser to the flowmeter, depending on the size.

Advantages of the vortex ERVIP MASS METER flow meter:

  • the ability to measure both the volume flow and volume of liquid and gaseous media, as well as the mass flow and mass of liquid, as well as the density of liquid;
  • no moving parts;
  • preservation of the connecting dimensions of turbine meters TOR;
  • the converter implements an algorithm of a "floating" coefficient depending on the flow rate (frequency), which, in turn, increases the accuracy of measurement over the entire flow range;
  • can be used to measure the flow rate of both liquid and gaseous media;
  • low cost in comparison with coriolis flowmeters providing comparable functionality.
