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 I/P Transducer accepts an electrical input signal and produces a proportional pneumatic output.In this session we are going to discuss about how I/P transducer works. To know about I/P converter calibration Principle of Operation Electronic Circuit The input current signal i.e. 4-20 ma is received by the transducers electronic circuit and compared to the output …
Introduction Bourdon tube uses a coiled tube which as it expands due to pressure increase causes a rotation of an arm connected to the tube Working principle The pressure sensing element is a closed coiled tube connected to the chamber or pipe in which pressure is to be sensed. As the gauge pressure increases the tube will tend …
Wire-guided float meter detector is a buoyancy type level measurement technique. For large level measurements (ie. 20m), wire-guided float detectors can be used. Basically, the function of bouncy type meters is that to use floats in the tank and record the float movement as the level in the tank raises. Working: The guide wires are …
Introduction Boiler Controls are specifically designed equipments that maximize the efficiency of new and / or existing boiler and burner plant. Boiler Controls equipment is considered to include the following: Oxygen Trim Controls Oxygen trim controls automatically monitor the oxygen or carbon monoxide concentration in boiler flue gases and vary the air/fuel supply to the …
Introduction Differential Pressure Transmitter convert pressure measurements into a proportional 4-20 mA or a 1 – 5 Vdc output signal that functions as the input to a controller, recorder, indicator or similar device. These transmitters find application in the gas, water, and process industries that require accurate measurements over a wide range of environmental conditions. Theory …
Capacitance is one of the most common forms of humidity measurement. Humidity sensors are typically used in building controls. The most effective location for a wall mounted sensor is near the return air duct, where the air leaving the room has the best averaged humidity. Principle: Capacitive Humidity instrument uses the principle of capacitance equation C – …
Definition A pressure gauge is a mechanical instrument. It is designed to measure the internal pressure, vacuum of a vessel or system. There is lots of variety of pressure gauges in the market according to size, styles. Principles of Operation Bourdon tubes are the main pressure sensing element used in most of the pressure gauges When the …
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 …
