Portable Flow–meter Testers RxxxP and RxxxPTM
The portable flow – meter testers RXXXP and RXXXPTM are independent autonomous high–efficient and precise devices designed for performance of a quick verification or adjustment during the manufacturing process of water – meters produced according to ISO 4064 or EN14154. The test could be performed on site, even without dismantling of the water–meter under test.
The portable testers RXXXP and RXXXPTM consist of calibrated reference meter, an electronic unit with microprocessor, keypad and display and inlet–outlet flow–control fittings. A comparative method of verification is used – that means that the volume measured by the water - meter under test is compared with the volume measured by the reference meter of the tester.
The test mode is “Flying start”, thus the error from starting and stopping of the flow is eliminated.

The portable testers RXXXP and RXXXPTM are easy to mount and convenient for work. The following possibilities are available:
- Water meter verification on site with no need of dismounting the water-meter under test.
- The flow –rate is adjusted manually with a closing valve.
- When the measurement starts, the operator can observe from the display the outflow of the liquid, the flow-rate and the temperature of the water in real time.
- At the end of the measurement the relative error of the water-meter under test in[%] is indicated. There is also indication of the average flow-rate in [m3/h], the duration of the measurement in [s] and the passed amount of liquid in [m3]
The resolution of the display is:
- Water meter error – 0.01%
- flow rate – 0.0001 m3/h (0.1 l/h)
- water volume – 0.000001 m3 (0.001 l)
- test duration – 0.01 s
- temperature – 0.1°C
The range of portable flow-meter testers includes the following two types: RXXXP with mechanical reference meter and RXXXPTM with electromagnetic reference meter
