Mechanical water flow meter types.

In the water distribution industry mechanical drive woltman type turbine flow meters continue to be the standard. Flow meters are also known as flow gauges. These turbine meters use a gear train to convert the rotation of the rotor into the rotation of a vertical shaft. Electromagnetic meters also known as mag meters are a variant of velocity type water meters.

Designed to measure the exact quantity of dispensed liquid fuel or lubricant for non commercial use. The most common type of the above listed mechanical flow meters utilizes a turbine that rotates as the flow of water applies a force to the blades. These can in turn be gear meter figure 1 or oscillating piston or nutating disk meter type. These measure velocity using electromagnetic properties instead of the flow through mechanical measurement mechanisms.

Gear type water flow meter. Operations of mag meters are based on faraday s law of induction. The rotation of the turbine is proportional to the velocity of the fluid moving past it. Flow meters are flow measuring instruments used to measure the linear nonlinear mass or volumetric flow rate of a gas or a liquid.

The piston is held in place at the base of the cone in the no flow position by a calibrated spring. Types of flowmeters flowmeter types. The disadvantage of mechanical water flow meters for water measurement is that they may clog up when the. A flow meter is a device that measures the flow rate of a fluid.

The shaft passes between the metering tube and the register section through a mechanical stuff. Generally all residential water meters are of positive displacement type. Spring and piston flow meters piston type flowmeters use an annular orifice formed by a piston and a tapered cone. 27 11 425 2094.

Reliable economical and easy to install and calibrate on site. The mechanical types of water flow meters work by measuring the speed of water flowing through the pipe that causes a piston or turbine to rotate. Once the velocity is known the flow can be calculated. The volumetric flow rate of the water is proportional to the rotational speed of the blades.

Magnetic flow meters commonly referred to as mag meters are technically a velocity type water meter except that they use electromagnetic properties to determine the water flow velocity rather than the mechanical means used by jet and turbine meters mag meters use the physics principle of faraday s law of induction for measurement and require ac or dc electricity from a power line or. Ultrasonic bulk water meters sales email. Water meters can be classified into various types depending on the mechanism by which they measure the flow of water.
