A Woltman water meter is a type of flow meter that measures the volume of water passing through a pipe. It is based on the principle of a turbine that rotates with the flow of water. The rotation speed of the turbine is proportional to the water velocity, and the volume is calculated by multiplying the speed by the cross-sectional area of the pipe.
A Woltman water meter consists of three main parts: a body, a measuring insert, and a register. The body is made of metal and has flanges or threads for connecting to the pipe. The measuring insert contains the turbine and a transmission mechanism that transfers the rotation to the register. The register is a device that displays the total volume of water that has passed through the meter.
A Woltman water meter is suitable for industrial, waterworks, water distribution, water monitoring, and agricultural applications where high flow rates and large pipe diameters are involved. It can also be used for billing purposes if it is calibrated and certified according to relevant standards.
