  Level measurement Level switch Types of level switch Different types of level switch are used in industries as requirements and functioning in the process control some mostly uesd types of level switches are listed here 1. Floats type level switch 2. Rotary type level switches 3. Vibrating level switch  4. Capacitance type level switches 5. Radio frequency type level switches Point level It is used to measure whether level of material is belowbor high than a specific point.    outputs of level switch is used as alarm or tripping purposes of pump, screw conveyor and belt conveyor. Float switch Float Switches Applications & Installations  A simplex (one pump) system will use a single switch wired in series with the motor leads so that the switch directly starts and stops the pump motor. Three main classification of mounting the float level switch are 1. side-mounted 2. Top-mounted 3. external-mounted  float switches. Displacer Switches  Displacer r...

  What is mass flow measurement Mass flow meter measures flow rate of the fluid through the pipe. Mass flow meter does not measure the volume. The mass flow rate is the mass of fluid that passes by a fixed point per unit of time. Mass of the fluid can be determine by using this type of flow meter. By measuring the density of fluid this flow meter measures the mass.  The Mass flow is proportional to density, cross-sectional area through which the substance is flowing, and velocity of fluid. This mass flow meter is very accurate and it is used to measure the flow of gases and fluids.  Types of mass flow meter What are the types of mass flow meter  How mass flow meter work Coriolis and thermal flow meters are two types of a mass flow meter. A mass flow meter is required for the accurate measurement of the mass related processes such as chemical reaction, heat transfer . Thermal flow meter In thermal flow meter a thermostat is used to measures the mass of the fluid fl...
