Overview

HT-100F Series is a Float Type Level Transmitter installing on the top of tank measures liquid levels continuously. Especially, it is easy to be installed to where the space between top of tank and ceiling is narrow at the site.

Characteristics

- Widely used to measure liquid levels

- Remote control and local indication are available.

- Easy installation to where the space is narrow

- Strong structure and easy maintenance

- NAMUR NE43 is applied.

Operation Principle and Composition

- A float which is manufactured according to a specific gravity of a medium moves upward or downward with a same liquid level in a tank by buoyancy and a wire which is connected to a float is wound up to wire drum by a constant spring. The rotation of wire drum is transmitted to a gear system, operates indicator pointer. A magnet which is installed on the indicator pointer activates reed switches and changes a resistant value. This resistant value is transmitted to the R/I converter and it converts the resistant value to a current signal, DC 4-20mA continuously.
