DESIGNATION FOR REQUISITIONING
When ordering the flow rate type, measurement limit in m3/h, medium measured - liquid, version, location category and secondary device type should be specified.
EXAMPLES
РЭВ-0, 025ЖУ3– electric explosion-proof flowmeter with upper measurement limit for water of 0.025 m3/h for temperate climate, location category 3 according to ГОСТ 15150-69.
Number in Public Register 5798-89
Recalibration interval 5 years
PURPOSE
Flowmeters of the РЭВ type ГОСТ 13045-81 are designed to measure volume flow rate of smoothly changing homogeneous flows of clean and slightly polluted liquids with dispersed foreign particles neutral to steel 12Х18Н9Т ГОСТ 5632-72 and to convert it into inductance "L" through differential transformer communication within the limits -10 £ 0 £ 10 МHz. They are designed for operation in dangerously explosive rooms and have explosion protection of transducers ВЗГ (according to ПИВЭ gradation).
Flowmeter calibration is individual and is performed by the Manufacturer individually for water with water and ambient air temperature of 20°С ± 5°С.
