High-sensitive liquid-sealed water meter

Product Description

This water meter is the latest product developed by this ***** product is provides with the stability and reliability of the common water meter , and with very sensitive start flow, up to 2L//H, usually called drop water meter. ***** bound 1. Maxiumum flow(Qmax)-top limit flow for the water meter.during the maximum flow , the water can used only for a short time. 2. Nominal flow(Qn)-the flow for a long time. 3. Transitional flow(Qt)-the flow for the water meter to be corrected for error. 4. Minimum flow (Qmin)-lower linlit flow for the water meter. 5. Start flow (Qs)-the flow for the water meter to begin the continous indication, and this time the water meter does not count the error of the indicated value. ***** curve ***** lower zone from including of the minimum flow to excluding the transitional flow:±5%. ***** upper zone from including the transitional flow to including the maximum flow:±2%. ***** applicable:***0°c ***** pressure:≤1.0Mpa.
