Horizontal Woltman Dry Dial Cold Water Meter (LXL-40E~LXL-200E)

Technical standards: GB/T 778.1~778.3-2007,JJG 162-2009
Functions:1.Flow Rate Performance: Basic meter technology and production craft comes from German. The special degisn ensures the sensitivity of Low District and current performance of High District of water meter. Model WS Vertical Woltman Large Caliber Water Meter concentrates the advantages of Horizontal Woltman Water Meter and Rotating Vane Water Meter. Adopting full flow detection, the measured water flow is axial water flow, low in and out, high measurement accuracy. Especially at low flow rate, precision is higher than other types of water meters. Stainless steel built-in filter design ensures the product can work stable and long life. WPHD model is suited for strong flow rate with U0 and D0 highest standard. Inner cavity can control water flow and reduce the accuracy affected by elbow, T type pipe, water filter and valve;
2.Ingress Protection: Using advance copper sealing technology to ensure water meter will be affected with damp. Ingress protection is IP68;
3.Correct Reading data: Adopting Infrared photoelectric transmission to get data which will not be affected by light and vibration caused by pipe or other elements;
4.Safe Use: The strong electric power source is physically separated from the water meter, and the insulation strength is high to ensure safe use;
5.Reading Accuracy: The sensor is non-magnetic and non-contact which will not affect the accuracy of original water meter;
6.Remote Transmission: Using M-bus and RS485 port to transmit data. Thers is no battery inside water meter. Short time power is provided by collector when meter reading is needed;
7.Easy to Maintain:The electromechanical conversion module adopts the plug-in design, which can be installed separately from the water meter. The module has strong versatility and is fully interchangeable. It can be transplanted between two water meters;
8.Strong Compatibility: Support a variety of standard communication interface output, easy and fast access to a variety of management scheduling systems.Spec for Horizontal(Vertical):ItemUnitParameterDNmm506580100125150Q4m³/h78.75(50)78.75(50)125
