Product Description

Product Description

Sight glass level gauge

Reflex glass level gauges working principle is based on the light refraction and reflection laws. Reflex glass level gauges use glasses having the face fitted towards the chamber shaped to have prismatic grooves with section angle of 90°. When in operation, the chamber is filled with liquid in the lower zone and gases or vapors in the upper zone; the liquid level is distinguished by different brightness of the glass in the liquid and in the gas/vapor zone. The reflex level gauges do not need a specific illumination: the day environmental light is enough. Only during the night an artificial light must be provided. Applications Reflex glass level gauges can be used in most of the cases and offer great advantages in terms of: low initial cost, low operating cost, easy level reading.
 

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. To avoid leakage in case of glass breakage, safety ball-check device can be provided in cross-fittings or shut-off valves. This kind of indicator is suitable for water/steam. To protect glass surfaces from corrosive action of the process fluid, Transparent Level Gauges can be fitted with Mica shields or Polytrifluorochloroethilene shields. This kind of indicator is suitable for liquids colorless and very fluid.

Installation

If the meter without light equipment, it can be installed at the light bright place.
The flange and the sealing face can't be damaged for contaminated.
If the measure range is very wide and must use serious meter to measure, their installing place should be separated without blind zone.
When use the level gauge, water pressure should be check firstly, and the pressure the meter can bear is no more than 1.5 times of the maximum pressure. The test must conform to the pressure vessel safely requirement of the relative department.
When install series TBS meter, the top and bottom needle valves must be closed. When operating, firstly open the top needle valve to its maximum degree and then open the bottom needle valve slowly to lead the fluid into the meter. And then loose the vent valve to vent gas. After vent out the gas then tight the vent valve immediately. When turning the needle valves.

Regulation for operation and maintenance
According to the clearness of the fluid to clean the needle valve regularly to ensure the liquid free-flow. The inner side of the glass plate can also be unload to clean when be contaminated. But the test must do every time when take off the plate and washing.
When vent air and drain the soiling should be careful to operate to prevent fluid overflow.
When glass is broken by accident, please close the needle valves or tube valve immediately.
When water level meter is used, should be preheated 20-30 minutes, when the glass plate with a certain temperature, when open on both ends of the valve, the infuse water or other medium.
During the use process, please often discharge the drainage, avoid fouling corrosion blocking channels, appear false water level phenomenon.
When replace glass, the metal filings and debris should be removed from the sealing surface.
Flat water level gauge (also called a level surface indicator), it is suitable for industrial steam boilers and steam locomotive boiler and water storage set on liquid level indicating.
Prism (or glass) must be under the equal compression when tighten thread. Tight each screw on turn several circles until to tighten torque 20-39.4 Nm.
