LEVEL INDICATOR
MOD. 1218-B and related variants (1121-H, 1121-B, 1337)
The level indicators with gauge board are recommended for their low cost, simple installation and rugged construction.
The level indicator consists exentially of a float connected to a counterweight through a Stainless Steel cable; the cable slides on Stainless Steel pulleys mounted on PTFE bearings and housed in a gas tight case. The float is guided through two Stainless Steel wires that are kept in tension by two spring-type tensioners.
The indicator counterweight is guided by two Stainless Steel wires to avoid contact with the gauge board.
For an easier handling and installation, the gauge board is supplied with two meters long elements; the gauge board is marked every centimeter and numbered every meter.

LEVEL INDICATOR MOD. 1218-B
This level indicator is used for non-pressurized tanks
LEVEL INDICATOR MOD. 1121-B This level indicator is used for pressurized reservoirs, the liquid seal housings are in cast aluminium and suitable for pressure of 130 mmH2O (standard type) and 330 mmH2O (extended type)
LEVEL INDICATOR MOD. 1121-H This level indicator with modular liquid seal is used when the tank pressure exceeds 330 mmH2O, since the oil seal pipes can be made as long as necessary or when the oil seal housing must not be in cast aluminium
LEVEL INDICATOR MOD. 1337 This level indicator is used for floating roof tanks
