Flow switch

  Flow switch The flow switch is designed to monitor the flow of air, liquid or steam. The device transmits a trip signal through to another device in the system, called a pump. Flow switches are typically built to indicate to the pump regarding shutting off or to turn on. A flow switch has several different uses.  Flow Switch is a mechanical switch that is switched on or off in response to the flow or non-flow of a fluid such as air or water. The switch typically operates through the use of a paddle which gets displaced due to the force of fluid moving past it. flow switches are used to determine if the flow rate is above or below a certain flow rate. This value (the set point) can be fixed or adjustable. When the set point is reached, the response can be the actuation of an electric circuit. Why Flow switch Shows wrong indication ? The below are the possible causes for the false activation of flow switch : Entrapped air or gas. Turbulence in tubing or unit Mechanical se

Flow Meter

Flow meter A flow meter is basically a device used to measure or indicate the flow of a liquid, gas or any fluid moving through a pipe. A flow meter basically measures the amount of steam, liquid and gas flowing through a pipe, and there are several types of flow meters or flow sensors that measure the flow rate of a liquid or gas.  A flow meter measures the flow of a gas or liquid through a closed or open pipe. Basically flow is the amount of liquid or gas passing through a pipe or system and the formula for measuring flow is Q=V*A where Q is the flow rate, V is the flow velocity and A is the pipe area. And the unit of flow measurement is liter/minute, m3/hour, cut/second, kg/second, ton/hour, gallon/minute. flow Flow is the flow of a gas or liquid through a closed or open pipe. And basically flow is the amount of liquid/gas passing through the system. The unit of flow is liter/minute, kg/second, gallon/minute, tans/hour, m3/hour. flow rate Flow rate is equal to the velocity of flow i
