In September 2013, EMIS-VIHR 200 PPD was installed at BKNS No4 of NGDU UFANEFT.

During the trial operation, the device has proved itself as a reliable measurement equipmnet; The technical parameters declared by the manufacturer are fully confirmed. Compared with similar used devices, the tested EMIS-VORTEX PPD flowmeter showed such technical advantages as: stability of measurements with heterogeneous media, high durability against mechanical impurities and aggressive chemical elements.

It should be noted that this device is completely interchangeable in overall dimensions and installation method with other reservoir pressure maintenance metering devices, which significantly reduces the cost of equipment installation.
