Flow Meter Sirus LCTA is a volumetric meter for continuous or intermittent measurement and control of liquid flow in a pipeline. It has many advantages, such as large range, high accuracy, small pressure loss, strong viscosity adaptability, measurement of high temperature and high viscosity liquid, convenient calibration, installation suggestion and so on. It is suitable for flow measurement in petroleum, chemical, chemical filter, transportation, commerce, food, medicine and health departments.
LC Series oval gear flowmeter is equipped with a pointer and printing wheel accumulation device, and can directly display the liquid accumulation flow through the pipeline on the spot. The accumulative, quantitative and instantaneous flow remote transmission control can be realized by attaching the transmitter and the electric display instrument to the counting mechanism. High temperature and high viscosity liquid can be measured by adding radiator or ellipsoid undertooth.
The flowmeter for different liquids (acids, bases, salts, organic solution, etc. ) can be made of different materials.
Structure and Working Principles
Oval gear flowmeter consists of flow transmitter and counting mechanism. A high temperature flowmeter if formed if a radiator is installed between the transmitter and the counting mechanism. The transmitter consists of a metering chamber and a sealing coupling with a pair of elliptical gear rotors. The counting mechanism comprises a deceleration mechanism, a regulating mechanism, a counter and a transmitter.
Structure Diagram
The metering chamber has a crescent cavity composed by a pair of oval gear and cover plate as the metering unit of flow. The oval gear is rotated by the pressure difference between the inlet and outlet of the flowmeter so that the liquid is continuously measured by the crescent cavity and sent to the outlet. The liquid that flows every turn is four times of the crescent cavity. By sealing coupling, the total number of turns of oval gear and the speed of rotation are sent to the counting mechanism or transmitter. Thus, we can know the total amount of liquid and instantaneous flow through the pipeline.
