WHAT'S WATER METERWater meter is a device that record the volume of water use by the flow passing through the meter chamber. most of which are accumulative flow measurements of water. They are generally divided into two categories: volumetric water meters and velocity types water meters. They originated in Britain. The development of water meters has a history of nearly 200 years. When choosing the specifications of water meters,Website:http://www.china-watermeters.com, The size and range of the flow used under normal conditions should be estimated first, and then the water meter of the specification closest to the value of the normally used flow should be selected as the first choice.TECHNICAL TERMQ1(Min. Flow Rate L/h): The indication value of the water meter is required to conform to the minimum flow rate of the maximum allowable error.Q2 (Transitional flow rate L/h)): Between the commonly used flow Q3 and the minimum flow Q1, the flow ......url:http://www.china-watermeters.com
