TU 4213-00849652808-2004

Flow meter  

Designation and options:

Flow meter is designed for volume flow rate of: fresh, technical, produced (from oil processing units) water, formation water in the field without field network of electrical current, for example on the injection wells.


  • Primary instrument (sensor) PPRE-32×21 (PPRE-32/100×21), PPRE-65×21 (PPRE-65/100×21), PPRE-100×21
  • Portable secondary instrumentBIP-16 with independent power supply designed for volume flow rate in the field conditions; register for 16 measuring objects

Principle of action:

Measuring of the electromotive force induced by geomagnetic field in the conducting fluid proportional to the average speed of the flow.


  • Wide range of operating pressures (up to 21MPa)
  • Operation with the increased gas ratio
  • Operation with high flow inhomogeneity near pipe bends, adjustable chokes, back pressure valves and gate valves
  • Absence of structure elements in the flow through. Pressure drop doesn’t exceed pressure drop in the pipelines of the same length
