PENGARUH POSISI PEMASANGAN METER AIR RUMAH TANGGA PADA WATER METER TEST BENCH TERHADAP HASIL PENGUJIAN

Abstract

The water meter testing process by the Legal Metrology Unit is carried out on a water meter test bench which may consist of one or two test lines. Several water meters can be tested in series on each test. The position of the water meter installation on the test bench is one of the factors that can affect the results of the water meter test. This study aims to determine the effect of the installation position of the water meter on the test bench on the test results. Based on the test results that have been obtained on the water meter test in position 1 (close to the delivery faucet) and at position 2 (far from the delivery faucet) it can be seen that the effect of the largest error is in the flow of the minimum flow velocity Q1. The error value of the minimum flow rate Q1 in testing position 1 (close to the faucet) is 5.3% greater than the error in testing position 2 (far from the delivery faucet).
