An Analysis of the Difference Between Woltman Type Water Meter&Rotary Vane Water Meter

rp_280_257_67acfc4dd5178328bd34fc2cefb3f10f.jpgMeters are used to measure the flow of water. Water meters can be recorded for the consumption of tap, just put it on a meter. When someone is releasing water, the pointer on the meter or the wheel of the word will indicate the amount of the passage. This will also allow each user to clearly understand the amount of water they use, which can also save water. Therefore, the water meter has gradually entered every household. Today’s little series to introduce is the woltman type water meter and rotary-wing type water meter, below we together to analyze the difference between the two.
Woltman Type Bulk Cold(Hot) Water Meter

Introduction of the spiral-fin water meter

The rotor water meter is suitable for measuring the total amount of one-way flow of small-caliber pipes. such as the diameter of 15mm, 20mm specifications of the household water consumption measurement. The water meter mainly consists of shell, impeller measuring mechanism and deceleration mechanism, as well as the indicator table, with simple structure characteristics. There are many kinds, including mechanical designs without output. With signal output, with signal output is analog output, but also patented technology back-end digital design. In addition, the measurement principle of the rotary-vane water meter also has many kinds, for example, the flow-driven rotary wing drive gears to count. There are also some rotating wings to output 1 pulses per turn, followed by the circuit to statistics.
Upright Rotary Vane Wheel Removable Water Meter

Introduction of rotor water meter

Same as rotary-wing type Water meter (dn15-dn65), the spiral-winged water meter also belongs to a speed-type water meter. When the water into the meter, along the direction of the axial impact of the spiral vane impeller rotation outflow, the impeller speed and flow rate is proportional to the speed reducer after transmission, in the indicator device to show the total water through the meter.
Element Woltman Cold Water Meter
The difference between the woltman type water meter and the rotary-wing type water meter
Rotary-wing type water meter: rotary-vane meter is applicable to the measurement of the total amount of one-way flow of small-caliber pipe. such as the diameter of 15mm, 20mm specifications of the household water consumption measurement. The water meter mainly consists of shell, impeller measuring mechanism and deceleration mechanism, as well as the indicator table, with simple structure characteristics.
Horizontal woltman water meter: horizontal screw-wing meter used to measure the flow of large-flow pipeline total. Especially suitable for water supply and large mines. The main characteristics are large circulation capacity, small size, compact structure, easy to use and maintenance. The Spiral-winged water meter is generally used to measure the flow of large flow pipelines. So the general large enterprises and schools and so on will choose the spiral-wing type water meter, but the opposite is the rotary-wing-type meter is suitable for metering small flow of the total flow, so the household meters are generally rotary-wing meter. The use of water meters is also to do a supervision of our behavior, if you waste a lot of the waters, you will be responsible for this behavior. Therefore, it is necessary to use water meters widely.
