In the water distribution industry mechanical drive woltman type turbine flow meters continue to be the standard.
Mechanical water flow meter types.
Flow meters are flow measuring instruments used to measure the linear nonlinear mass or volumetric flow rate of a gas or a liquid.
These turbine meters use a gear train to convert the rotation of the rotor into the rotation of a vertical shaft.
K33 k44 k700k33 k44 k700 flow meters are with mechanical counter display.
Scales are based on specific gravities of 0 84 for oil meters and 1 0 for water meters.
The disadvantage of mechanical water flow meters for water measurement is that they may clog up when the.
Ultrasonic bulk water meters sales email.
These can in turn be gear meter figure 1 or oscillating piston or nutating disk meter type.
Once the velocity is known the flow can be calculated.
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.
The rotation of the turbine is proportional to the velocity of the fluid moving past it.
The shaft passes between the metering tube and the register section through a mechanical stuff.
The piston is held in place at the base of the cone in the no flow position by a calibrated spring.
Generally all residential water meters are of positive displacement type.
Designed to measure the exact quantity of dispensed liquid fuel or lubricant for non commercial use.
This article will provide the following information in short.
Water meters can be classified into various types depending on the mechanism by which they measure the flow of water.
Gear type water flow meter.
Reliable economical and easy to install and calibrate on site.
Types of flowmeters flowmeter types.
Electromagnetic meters also known as mag meters are a variant of velocity type water meters.
A flow meter is a device that measures the flow rate of a fluid.
Flow meters are also known as flow gauges.
Operations of mag meters are based on faraday s law of induction.
Types of water meters.
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.
The volumetric flow rate of the water is proportional to the rotational speed of the blades.
