A) Transparent level indicators are highly useful in chemical industries and petrochemical fertilizers. As the fluid is stored in high pressure and high temperature.

B) Reflex level indicators are for applications that involve high temperature, high pressure and use of corrosive fluids. The colourless fluid used in this apparatus gives better clarity to levelindication.

C) Magnetic level indicators have bi-colour indication. Cylindrical floats and powerful magnets are used to find the level of the fluid. The float movement is followed by magnetic capsules, and thus, the level in indicated.

D) Tubular Level Gauges are used to visualize the level in low or medium pressure application and mounted on the side of the tank / vessel.
