Water, Diesel, Oxygen, Oil, Fuel, Chemical, Solids

Level Measurement: In the modern manufacturing industries which use many solvents, chemicals, steam and other liquids, and the power plants which use vast amount of water, the accurate measurement of liquid level is very essential.


Medium: Water, Effluent water, Oil, Diesel, Furnace Oil, Fuel, liquid Oxygen, Chemical and Solids.

Application: Level Indicator, Metering, initiate an Alarm, start or stop a pump, open or shunt a valve at a high or low level

Instrument: Transmitter, Indicator, Gauges, Switches, Controller


Level Measuring Instrument (Direct  / Indirect)

Method: Continuous Level Measurement, Limit Level Measurement (max/min/mid, low/high)


A) Continuous Level Measurement: ( Full Range)

  • Measuring the level of substance in full range continuously, actual/ present level, exact amount volume, and accurate reading. It is best method of accurate measurement what is present value and how much quantity now. Easily integration with process controller, remote display indicator, PLC.
  • Direct Methods: Sight glass, bob and tape method in open tanks, tubular glass, Hook gauge, magnetic gauge. 
  • Type of measurement: Capacitive type, Differential Pressure, Pressure, Float type, Magnetic Contact, Ultrasonic, Radar,  etc.
  • Transmitter: Water Level Transmitter, Oil Level Transmitter, Fuel Level Transmitter, Oxygen Tank Level Transmitter, Chemical Tank Level Transmitter, Solid level Transmitter, Chemical Level Transmitter
  • Differential Pressure: DP Transmitter to liquid Oxygen tank level measurement, Water Level, Oil Level. Most suitable for Closed Tank, boiler drum, high pressure heater, pressurised vessel, water & Steam, Minimum error.

B) Limit Level Measurement: ( Max /Min /Mid, low/high)
  • Limit Level Switch: Magnetic float Sensor, Float type level switch Capacitive Level Sensor, Float type switch, Over flow Switch, low level Switch, high level switch, level Sensor, Water level sensor, oil level sensor, Diesel level sensor, fuel level sensor, Furnace oil level sensor, Water Level Switch, Oil level switch, Diesel Level Switch
