Technical Information

LT11/LT12/LT14/LT16 Float Gauge

Mechanical tank gauge for accurate and reliable level

measurement

Application

The LT series of float gauges have been developed

for use in all areas of industry. Many years of

operation in a wide variety of applications have

proven their reliability.

Typical application includes:

• Level indication of petroleum products such as

crude oil; kerosene; light and heavy oil,

vegetable oil, palm oil, seed oil and animal oil

• Highly viscous liquid such as asphalt

• Certain chemicals (corrosive/toxic vapor can be

sealed using a liquid seal pot)

• Liquid gas measurement a spherical tank

Benefits

• No electrical power is required to perform the

measurement

• Built-in repeatability check

• Direct reading at the tank side allows you to

check the tank contents easily

• Can be installed on a variety of tanks including

fixed roof, floating roof, covered floating roof

and spherical tanks

• Can be used in conjunction with

analogue/digital transmitter to perform tank

inventory management

Function and system design

Measuring principle The float gauge consists of a float, measuring tape,and the gauge head. When the float is immersed

in the tank liquid, it is balanced by its own buoyancy and the tension of the measuring tape. This

measuring tape is wound around a drum, which is located inside the tank gauge

head with given tension by the spring motor.

When the liquid level changes, the change in the float buoyancy is detected and the 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 interval. As the tape rotates the sprocket, it activates the

display indicator.

The position of the measuring tape holes on the sprocket compensates for the tape weight and

prevents the tape from slipping. To provide analogue or digital outputs, a transmitter can be coupled

directly to the sprocket wheel and attached to the back of the gauge head.

Accessories

Anchor weight The anchor weight is used for keeping guide wires

in applications where the fixed anchors have not been

installed.

Material: SS400 or SUS316

Weight: 23 kg.

Seal pot for LT 11/12 Seal pot prevents toxic or corrosive vapors

escaping from the tank via the gauge installation.

Seal liquid: e.g. liquid paraffin or spindle oil

Max seal pressure: 0.4 bar/ 1150cc

Shape: U-shape

Process connection: thread or flange

Material: AC4A+SGP, SUS 316 or PVC

Refer to page 15,16.

Crank device The crank is attached to the gauge head and enables the

float to be raised or, lowered manually.

This is particularly useful on large tanks or other

situations where turbulence is expected.

Pipe supporter Pipe support is used to attach a pipe to the tank.

Material: SS400
