Test bench with sonic nozzles for residential gas metersSZKD G1,6 – G6
Test benches with sonic nozzles for residential gas meters SZKD are used for verification of residential gas meters size G1,6 ÷ G25. Complete testing bench includes two lines (arms) with 5 fixing places of gas meters on each line. If the needs of capacity are lower, it is possible to deliver test bench with only line.
Test benches are equipped with a exchangeable jig with a set of sonic nozzles consisting of 3 sonic nozzles for flow-rates Qmax, 0,2 Qmax and Qmin for one size of gas meters. When testing any other size of gas meters, it is very simple to change the set of nozzles. The testing bench is operated by one operator controlling all functions through computer. The whole testing process is shown on the screen of the monitor, where all actual values and parameters can be seen and recorded. Software running under operation system Windows 98 enables to use various functions of statistical evaluations, saving data and recording (print) the report about the test.
