Introduction A rotameter measures the flow of liquids, gases and steam by using a float inside a conical tube. The rotameter principle is one of the oldest and most mature principles in flow measurement. The space between the tube and the float is larger at the top to allow more flow through the meter. As …
Why use square root extractor for DP transmitter? The DP flowmeters measure the differential pressure across the constrictions made in the flow channel. The differential pressure measured has nonlinear relation with flow through the pipeline. Differential pressure developed by a venturi, orifice plate, pitot tube, or any other acceleration-based flow element is proportional to the square …
The primary devices used in open channel flow measurements are weirs and flumes. Unlike the flow through the closed channel, the height of the flow level is measured in relation to the flow of open channel flow. Open channel flow meter working Principle: Liquid flow is based on the principle of energy. Two types of …

Rotameter is a variable area flow meter, works for measuring the flow of low viscous fluid at high velocity. A variable-area flowmeter is one where the fluid must pass through a restriction whose area increases with flow rate. Principle: It works on the principle of upthrust force exerted by fluid and exerted by gravity. The flow …
Introduction The TORBAR is a multi port self-averaging flow meter. Its designs is similar to the pitot tube (which is used for fluid flow measurement). Many industries have been used TORBAR since 1985 How TORBAR Works According to the flow rate in the pipeline Torbar produces a differential pressure i.e. proportional to the square of …
Coriolis flowmeters are mass flowmeters, which measure the mass of fluid passing through a pipeline unlike the other volumetric flow meters, which measures the volume of the fluid passing through the pipeline. Coriolis mass flowmeter provides direct, in-line and accurate mass flow measurements that are independent of temperature, pressure, viscosity and density. Mass flow, density and …
Introduction Sonar flow technology is a new member to the industrial flow meters.sonar flow measurement principles is distinct from all conventional flow meter technologies. SONAR flow meters utilize sonar-based array processing techniques to listen to, and interpret pressure fields generated by turbulent pipe flows. How Sonar Flow Meters Work The first method is to …
The Orifice plate is differential pressure flow measurement device. An orifice is simply a smooth disc with a round, sharp-edged inflow aperture and mounting rings. Principle: When an orifice plate is placed in a pipeline carrying fluid, the orifice plate is installed perpendicular to the flow of the fluid to be measured. As all DP flowmeters, …
Magnetic flowmeters are velocity type of flowmeters. An electromagnetic flowmeter can work with almost all liquids and slurries, as long as the liquid being measured is electrically conductive. Electromagnetic flowmeters can be employed to measure more or less all electrically conducting fluids, pastes, slurries, acids, lyes, juices and emulsions including fluids with a conductivity as low as …
INTRODUCTION Venturi tubes, flow nozzles, and flow tubes, like all differential pressure producers, are based on Bernoulli’s theorem. General performance and calculations are similar to those for orifice plates. Modern precision manufacturing techniques allow much greater accuracy of the coefficient for venturi tubes and flow nozzles computed from dimensions, and the coefficients are only moderately less …
