Flow Rate Measurement Devices

Kinds and units of measurement.

Flow rate measurement devices.

For the measurement of flow rate of liquid the method used is a. Flow measuring device 4. The orifice size can be changed by replacing different orifice plates. Round ducts log linear traverse for round ducts two diameter approach.

In the simplest method a current meter turns with the flow of the river or stream. The grid lines which lay out the duct flow measurement points are traverses. Coefficient of discharge is 0 60 to 0 64. These measurements are related by the material s density the density of a liquid is almost independent of conditions.

Orifice nozzle and venturi flow rate meters the orifice nozzle and venturi flow rate meters use the bernoulli equation to calculate fluid flow rate using pressure difference through obstructions in the flow. Flow meter is a device that measures the rate of flow or quantity of a moving fluid in an open or closed conduit. All of these. Flowmeters and turndown ratio rangeability turndown ratio for flow measurement devices like orifices venturi meters etc.

In this article we will try to look at each category with brief details of particular devices that fall under that category. You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters. The devices used for flow obstruction is are a. The current meter is used to measure water velocity at predetermined points subsections along a marked line suspended cableway or bridge across a river or stream.

Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates with units such as liters per second or kilograms per second respectively. The device is very simple and can be easily installed. This is another device for the measurement of flow in pipes. Achieve precision flow measurement and process control flow measurement is the process of measuring fluid in your plant or industry.
