Turbine flowmeter is a volumetric measuring device Posted by : admin / Posted on : Sep 02, 2022

The Turbine flowmeter is a volumetric flow measurement device. It uses a magnet pick-up sensor to measure flow volume. Its low pressure loss and accuracy make it a popular choice for measuring gas and liquid flow rates.

Turbine flowmeters are volumetric measuring devices that are designed to measure the volumetric flow of fluids. They work like a windmill, with a rotor that rotates on a parallel axis of symmetry. As the media passes through the turbine, the blades rotate in turn, each passing a sensor. The speed at which each blade rotates is directly proportional to the volumetric flow. The meter can be equipped with a magnet pick up, photoelectric cell, tachometer, or other devices that can provide a signal.

A turbine flowmeter is very accurate and precise. It works by detecting a pulse from the flow. The more rapid the flow, the larger the pulse. The sensors are placed externally to the flowing stream. This allows the flow to pass through without creating material constraints.

A turbine flowmeter uses a magnet pick up sensor to measure fluid flow. The magnetic field created by the turbine causes alternating current to flow through the meter. The frequency of the alternating current is proportional to the rate at which the blades move. The meter also has a photoelectric cell that senses the motion of the turbine blades. The sensor picks up these electrical pulses and counts them over a period of time. The totalized pulses are then used to calculate the speed of rotation of the turbine.

There are many types of pickup sensors for turbine meters. Some are electrical, while others use magnetic drives and gears. There are also mechanical pickup sensors such as Hall-effect sensors and reluctance pickups.

These flowmeters can measure a wide range of fluids, including liquid natural gas, water, and blood. Their electronics use a mathematical equation that describes the flow rate based on the speed of sound through a fluid. Once this information is input into the flowmeter, the electronics calculate the volumetric flow rate.
