FLOWMETERS FOR LOCAL FLOW RATE MEASUREMENT WITHOUT REMOTE READING TRANSFER РМ, РМФ

 
PURPOSE
Flowmeters of the РМ, РМФ type ГОСТ 13045-81 are designed to measure volume flow rate of smoothly changing homogeneous flows of clean and slightly polluted liquids and gases with dispersed foreign particles.
Tropical and marine versions are available to order.
Flowmeters of the РСБ type are designed to measure flow rate of oil in a centralized lubricating system of paper-making machines.
 
 
DELIVERY SET
 
а) flow meter – 1 pce;
b) operating manual – 1 copy;
с) data sheet – 1 copy.
 
Number in Public Register 3375-82 (PM)
                                       4568-74 (РМФ)
 
Recalibration interval    5 years
 
 DESIGNATION FOR REQUISITIONING
 
When ordering the flow rate type, measurement limit, medium measured (Ж - liquid or Г - gas), version, location category, type of connection should be specified.
 
Examples
 
РМ-0,04 ЖУЗ-1 - flowmeter of the РМ type with upper measurement limit for water 0.04 m3/h for temperate climate, location category 3 according to ГОСТ 15150-69, 1 – pipe connection (for PM-II).
РМ-0,1 ГУЗ-K – flowmeter of the РМ type with upper measurement limit for air 0.1 m3/h for temperate climate, location category 3 according to ГОСТ 15150-69, K – with calibration.
