FAQ

Q: How does a Woltman water meter work?

A: It operates based on the rotation of a turbine. As water flows through the meter, it drives the turbine blades to rotate. The rotation speed of the turbine is directly proportional to the water flow rate, and the volume of water is calculated by multiplying the speed by the cross - sectional area of the pipe.

Q: Are Woltman water meters suitable for high - flow applications?

A: Yes, they are primarily designed for industrial, agricultural, and municipal settings where water demand is high. They can handle flow rates ranging from 1.5 to 10,000 cubic meters per hour and operate at high pressures up to 16 bar.

Q: Do Woltman water meters have good accuracy?

A: Yes, they have a high degree of accuracy. In the lower flow zone from Qmin inclusive up to but excluding Qt, the maximum permissible error is ± 5%. In the upper zone from Qt inclusive up to and including Qs, the error is ± 2% (± 3% for hot water meters).

Q: How should Woltman water meters be maintained?

A: Regularly check for leaks around the meter connections and inspect the meter for any signs of wear or damage to the internal components. Clean or replace the filter if installed. If the meter is not in use for an extended period, it should be drained to prevent corrosion.

Q: Can Woltman water meters be used to measure hot water?

A: Yes, there are specific models of Woltman water meters designed for hot water applications, which can withstand high temperatures. For example, some hot - water - meter models can handle water temperatures of up to 130°C.

Q: What is the working pressure range of Woltman water meters?

A: The working pressure of Woltman water meters is generally PN10 / 16 / 25, which means they can work under pressures of 10 bar, 16 bar, or 25 bar, depending on the specific model.
