Mechanical Water Flow Meter Types

Scales are based on specific gravities of 0 84 for oil meters and 1 0 for water meters.

Mechanical water flow meter types.

Electromagnetic meters also known as mag meters are a variant of velocity type water meters. The disadvantage of mechanical water flow meters for water measurement is that they may clog up when the. Gear type water flow meter. A flow meter is a device that measures the flow rate of a fluid.

The rotation of the turbine is proportional to the velocity of the fluid moving past it. Once the velocity is known the flow can be calculated. Generally all residential water meters are of positive displacement type. The volumetric flow rate of the water is proportional to the rotational speed of the blades.

Reliable economical and easy to install and calibrate on site. 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. Flow meters are also known as flow gauges.

Types of water meters. The piston is held in place at the base of the cone in the no flow position by a calibrated spring. This article will provide the following information in short. Operations of mag meters are based on faraday s law of induction.

In the water distribution industry mechanical drive woltman type turbine flow meters continue to be the standard. Water meters can be classified into various types depending on the mechanism by which they measure the flow of water. K33 k44 k700k33 k44 k700 flow meters are with mechanical counter display. These turbine meters use a gear train to convert the rotation of the rotor into the rotation of a vertical shaft.

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. Spring and piston flow meters piston type flowmeters use an annular orifice formed by a piston and a tapered cone. 27 11 425 2094. Types of flowmeters flowmeter types.

The shaft passes between the metering tube and the register section through a mechanical stuff. These measure velocity using electromagnetic properties instead of the flow through mechanical measurement mechanisms. 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.
