Flow Rate Measurement Devices

This is another device for the measurement of flow in pipes.

Flow rate measurement devices.

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. For the measurement of flow rate of liquid the method used is a. 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. In this article we will try to look at each category with brief details of particular devices that fall under that category. Kinds and units of measurement. Flow nozzle and dall flow tube d.

Thermal mass flow measurement view answer hide answer. Coefficient of discharge is 0 60 to 0 64. 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.

Flow meter is a device that measures the rate of flow or quantity of a moving fluid in an open or closed conduit. However a variety of advanced equipment can also be used to sense stage and measure streamflow. The orifice size can be changed by replacing different orifice plates. These measurements are related by the material s density the density of a liquid is almost independent of conditions.

The log linear method provides high accuracy 3 in flow totalization by measuring air flow closest the edges of the duct space preferentially. Flowmeters and turndown ratio rangeability turndown ratio for flow measurement devices like orifices venturi meters etc. You can measure flow through a variety of different devices such as coriolis differential pressure vortex magnetic ultrasonic turbine and positive displacement meters. All of these.
