The flow meter is designed to measure the mass (mass flow rate) of liquids, oil and gas mixtures, crude oil under GOST R 8.615-2005 and oil products (hereinafter referred to as the measured medium), and to use the information obtained for technological purposes and accounting.
The flow meter is used in automated metering installations, in stationary technological installations, ground mobile refueling and pumping facilities, in commercial metering systems.
Features & Benefits:
- Direct measurement of crude oil mass
- The opportunity of liquid measurement with free gas inclusions up to 95%
- The electric heating modification for high-viscosity liquids
The flowmeter can be used in both explosion-proof and explosive environments. The pulse sensor (pulse sensor with integrated computer) located inside the flowmeter is equipped with explosion-proof enclosure under GOST 30852.1 or intrinsic safety of "ia" protection level under GOST 30852.10. The electric heating device located on the flowmeter body has “e” type protection according to GOST 30852.8 and explosion-proof level "advanced explosion-proof reliability".
