HITROL CO., LTD
HLT-1112 (HLT-1212)
is a magnetic coupling type float level gauge which measures
liquid level in a tank, by movement of a weight in a guide pipe according to a
movement of a float, using a constant spring. Conventional level gauge is hard to be
applied for corrosive and/or toxic liquids due to a corrosive vapor which is develped
in a tank and comes up along a guide pipe to gauge head, can corrode inside
components in a gauge head. On the other hand, magnetic coupling type float
level gauge is a closed type and prevent an inflow of vapor into a guide pipe so it is
suitable for corrosive and/or toxic liquids.
• Applicable to a tank which has a pressure (Max. 5kg/cm
2
).
• Measurement in mm using spring balance
• Simplified design, high accuracy and durability
• Operating checkup using a Drive Checker
• Easy installation and maintenance
• Option for remote indication, control and switch for alarm
• Large scale dial enables legible indication even at a distant location.
The float in a tank floats on the surface of the liquid at the point which the float
weight and buoyancy are in equilibrium, and the magnet in the float sticks to the
magnetic in the weight which is installed in a guide pipe because the polarity of
them is contrary. When the liquid level changes, weight moves according to the
movement of the float and spring motor adjusts the measuring tape to maintain
the float position on the surface of the liquid. The measuring tape has a series of
holes set at regular intervals and as the tape rotates the sprocket, it in turn operates
the display indicator. The position of the measuring tape holes on the sprocket
compensates for the tape weight and prevents the tape from slipping.
