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.
