Flow Rate Measurement Devices

You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters.

Flow rate measurement devices.

These measurements are related by the material s density the density of a liquid is almost independent of conditions. 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. This is another device for the measurement of flow in pipes. 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.

The devices used for flow obstruction is are a. Thermal mass flow measurement view answer hide answer. The device is very simple and can be easily installed. All of these.

For the measurement of flow rate of liquid the method used is a. Flow nozzle and dall flow tube d. The log linear method provides high accuracy 3 in flow totalization by measuring air flow closest the edges of the duct space preferentially. The orifice size can be changed by replacing different orifice plates.

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. In this article we will try to look at each category with brief details of particular devices that fall under that category. Flowmeters and turndown ratio rangeability turndown ratio for flow measurement devices like orifices venturi meters etc. Flow meter is a device that measures the rate of flow or quantity of a moving fluid in an open or closed conduit.

Coefficient of discharge is 0 60 to 0 64. Kinds and units of measurement. The grid lines which lay out the duct flow measurement points are traverses. In the simplest method a current meter turns with the flow of the river or stream.

Round ducts log linear traverse for round ducts two diameter approach.
