Field of application

Float Gauge LT5 has been developed for all areas of industry. Many years of operation in a wide variety of applications have proven its reliability.

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).

Process temperature for low pressure version: -200 to +200°C (-328 to +392°F)
Process temperature for middle/high pressure version: -45 to +80°C (-49 to +176°F)
Measuring range: Maximum 30m (100ft)
Accuracy: ±2mm (± 0.08")

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 level indication 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 analog/digital transmitter to perform tank inventory management
LT5 has completely integrated internal mechanisms
Standardized guide wire and anchor design allow easy customer installation
