TRANSPARENT LEVEL INDICATORS

TRANSPARENT LEVEL INDICATORS

JMI manufactures Transparent Level Gauges employ two transparent glasses fitted with a liquid chamber on either side. The liquid level is indicated as a result of the difference in the transparent properties of the two media. For water/steam applications, an illuminator is mounted on the rear side of the gauge with its light rays deflected upward into the water column. This enables the observer to see the illuminated surface of the water as the light rays impinged on the surface of separation between water and steam are reflected the eye of the observer.

TRANSPARENT LEVEL GAUGE WORKING PRINCIPLE

Apart from glass tube level gauges, transparent level gauges are always fitted with two plate transparent glasses between which the fluid is contained. The fluid level is indicated as the result of the different transparency of the two media and in some cases (for water steam), by conveying upwards on to the surface of separation (between liquid and gaseous substances) a source of light located at the back of the gauge, the rays of which are totally reflected down to the observer.

TRANSPARENT LEVEL GAUGE APPLICATION

Transparent level gauges are suitable for almost all installations.

In fact, they permit:

  • The use of mica shields or Polytrifluorochloroethylene shields to protect the glass from the corrosive action of the process fluid
  • The observation of interface       
  • The observation of the liquid colour
