Products:
- manufacture, installation and service of electromagnetic meters of electroconducting fluids designed to be mounted on the pipes with a diameter range of 80-4,000 mm

The flowmeter is an up-to-date device for volume measurement and the measurement of volume consumption of the electroconducting fluids (water, mixture, pulp, ets.), running in the pipes with a diameter of 80 mm and over, within the temperature range of -2 C - +130 C. This is a small-sized and easy to install device (the installation of the device is 10-25 times as cheap as that of fluid flowmeters in operation). The flowmeter consists of the reorganizer ISP-204, which measures the velocity of fluid stream and transforms it into a unified signal (0.5 to 5 mA), the given reorganizer is recorded in the State Measuring Instruments List, item number U1190-90, - and the analogue concordance block BS-1 that is a secondary measuring-reorganizer. The storage and generalization of the exploitation process, the analysis of the impressions, proposals and wishes of the consumers enabled us to produce devices meeting the present-day standards. Taking into account demands of consumers, up-to-date modifications of the Block BC were designed, which are compatible with IBM PC/AT computers both as a separate block on the basis of PC or as a part of PC.

The consumption-counter works in the following operation conditions given in the table 1:

By now over 300 devices have been installed at the Ukrainian plants. All these devices have been highly evaluated. Among the plants using the flowmeters are:
JSC Obolon - 3 devices have been installed to keep the record of beer consumption and that of water in the artesian wells.
Druzhkovka Machine-Building Plant 3 devices have been installed to keep the record of water consumption (For 6 years they have been working without a break-down).
OJSC Crimea Soda-Making Plant on the pulp, containing 12% of hard components and up to 30% of salt within the temperature range of +8 +90 C.
Makeyevska Ukrpromvodchermet (they have been working for more than 5 years)
