Magnetic flow meter WOLTMANN

irrigationfor water

IRRIGATION METERS The Woltmann flowmeter is used to measure the total amount of cold or hot water consumed in civil, industrial and mining applications. - Flowmeter with Woltmann-type propeller with removable dial. - Dry quadrant with magnetic transmission device. - High quality components and materials to guarantee reliable and long-lasting performance, low pressure drop and long use life. - Accuracy in measurement conforms to GB / T 778 to 2007, ISO 4064 to 2005 Standard. - Interchangeability of the dial and clock between the meters in this line, without the need to disassemble the meter from the pipe for easy maintenance. - Fluid temperature: 0-40°C cold water meter, 0-90°C hot water meter - Humidity: <93% - Service pressure: ≤ 1.0MPa - Pressure drop: ≤0.1MPa - The liquid must meet national drinking water standards. - Woltmann type water meters must be installed following basic guidelines if an optimal measurement result is to be obtained. - By design, Woltmann meters are sensitive to the inflow profile, so the turbulence produced by the accessories or valves in the vicinity of the meter must be taken into account. - It is advisable to install a straight pipe section of 10xDN* in front of the meter and a section of 5xDN * behind it, for dimensions of 2” up to 12” (*DN= Nominal Diameter of the valve in inches). - Woltmann water meters have a dial with four markers, one main and three with wheels. - It is read in the following order: main (top-centre), right wheel (centre-right), down wheel (centre-down) and small marker (bottom-left) - Each marker has multiplication factors, which are always multiples or fractions of 10. If it is empty, we assume that the factor is X1. - To obtain a correct reading you have to follow the order of the second point and multiply each marker by the corresponding factor and add the 4 markers together at the end. - The final reading is always obtained in cubic meters (unit of volume). - Categories: Counters, Fertigation - Tag: product in English Technical characteristics / specifications: - Woltmann-type propeller with removable dial - Dry quadrant with magnetic transmission - High quality, long-lasting materials - Low pressure drop - Measurement accuracy: GB / T 778 to 2007, ISO 4064 to 2005 - Dial and clock interchangeable without pipe disassembly - Fluid temperature: 0-40°C (cold), 0-90°C (hot) - Humidity: <93% - Service pressure: ≤ 1.0MPa - Pressure drop: ≤0.1MPa - Compliant with national drinking water standards
