What is an Oil Flow Switch? The flow sensors, also known as “flow detector " or " Oil flow switch" are equipment for monitoring fluids in pipelines and work with the displacement of a magnetic piston that indicates the increase or decrease of the flow of liquid, activating the contact of a reed switch . The piston is controlled by a spring and returns to the initial position when there is no fluid, even if there is pressure in the pipe. How a Flow Sensor Works Our full range of flow sensors offer a selection of products for different types of applications, the sensors can be applied to water, oil and aqueous fluids (without solid particles) and have sensitivity adjustment for the flow to be detected, determining the point of flow at which the sensor will be activated. We produce a variety of sensors that serve from low to high liquid flow rates, with little or high viscosity.
The flow sensors are versatile, they allow the trigger flow to be configured in the part itself, that is why the same sensor can be used in applications of different flow rates (within the sensitivity range of the sensor), thus obtaining better control and monitoring of the fluids. Its use serves to detect the decrease or increase of the flow in pipes. Thus they are applied in the prevention of damage to pumps, bearings and equipment that must have a constant flow of some liquid material in the process. The flow sensor can turn off the equipment or simply point with a lamp or acoustic alarm.
To Know Sensors Better To choose the most suitable sensor (flow switch) in your application, take into account the following factors: Pipe size and system flow We manufacture flow sensors with connection threads from 1/8 "to 2" BSP, and are directed to the following categories: Low Flow (1/8 "and 1/4"), Medium Flow (1/2 ", 3 / 4 "and 1") and High Flows (1 1/2 "and 2").
The fluid in which the sensor is going to be applied Our sensors are recommended for use with water, oil and fuels. For application with chemical or corrosive products it is necessary that tests are carried out. We have models that deal with different viscosity rates of liquids Source Link – https://goldaircontrol.wordpress.com/2018/03/16/what-is-an-oil-flow-switch/
