General The device using the refrigerant vapor flowmeter method is
designed to test the capacities of compressors by measuring
discharged refrigerant vapor flow rate. Comparing with the
secondary refrigerant calorimeter method, this method has the
advantages of energy conservateion, low-cost and environmental
protection, etc. It conforms to standard GB 5773-86 and ASHRAE
23-78. Technical Specifications (we manufacture the devices according to users' needs, thefollowing is only for reference) 1. refrigerant:R22、R407C、R410A and R404A 2. capacity range:2,50015,000 W 3. repeatability:±1% 4. precision:±2% 5. working positions:1~4 6. control modes:manual and auto mode
