Korea’s top class Flow and Level Instruments manufacturer with 45 years of history
Overview
HT-100R Series is a Float Type Level Transmitter which continuously measures the liquid level in the tank by usage of buoyancy. This transmitter can be easily installed and adjusted, and can be especially applied for corrosive and acidic liquids with various anti-corrosive materials such as PVC or Teflon for the sensor. HT-100R Series is extensively used to measure liquid levels in various industries.
Characteristics
- Widely used to measure various liquid levels with high resolution (Resolution 10mm)
- Applicable to corrosive and acidic liquids with anti-corrosive material for the sensor (PVC and Teflon)
- Applicable to explosion area (Ex-Proof version)
- Strong structure and high reliability
- Local Indication is available. (Display Type)
- NAMUR NE43 is applied.
Operation Principle and Composition
As liquid level is changed in the tank, the float which is manufactured in accordance with the specific gravity of liquid moves upward or downward along the guide pipe with the same liquid level by buoyancy. The magnet is installed in the float and it activates reed switches that are installed in the guide pipe continuously, and activation of reed switches changes the resistance value. The variation of resistance value is transmitted to the R/I converter in the housing and it converts this resistance value to current output of DC 4-20mA continuously.
Specification
Float Application
Note : ◎ = Excellent ○=Good △=Acceptable X=Not good
* Above application can be different according to the specific gravity and the special medium.
Measuring Length
A = Upper Dead Band : Minimum length which cannot be measured from the bottom of flange
B = Measuring Range : It can be different according to the material.
C = Lower Dead Band : Minimum length which cannot be measured from the end of guide pipe
*If the measuring length is below than 600mm, the accuracy can be lower than described.

◈ Actual product may have a tolerance slightly.
■ Below drawing should be considered when installation.
|
Product should be installed at the place far from inlet in order to avoid the malfunction. |
Protection tube should be applied if there is a flow or slopping of the medium in the tank. |
|
Bracket should be installed with the product when the installation on the concrete as per above figure. |
Inner diameter ("d") of tank nozzle should be larger than the outer diameter of float as per above figure. |
