Float Level Indicator

Float-11 series are based on Archimedes Buoyancy Principle. Float rises and falls as the fluid level in a vessel changes. Due to magnetic effect, as the float moves, the proximal reed switches in the Float Level Indicator are magnified by the permanent magnet in the float and change the status from “open” to “closed”. The resistance value in the sensor changes linearly. The change of resistance value is then converted into 4 ~ 20mA standard DC output signal for remote detection and control. Float-11series can be made of different materials for fluids with different chemical properties. We also offer different floats for fluids with different density to reach the optimal measurement accuracy.


In Float-11 series products, high quality plastic reed switches are used. We emphasize manufacturing details and have also introduced full production process management and quality inspection to ensure our products reach super high reliability. In comparison with other similar products in the market, Jiwei Float-11 Level Indicator has the following advantages:

 Purchased high quality plastic reed switches from international market as its key parts, longer service life.

 LED display with high brightness, can be configured in horizontal or upright, convenient for observation under different conditions on site.

 Explosion proof certified for both Flameproof Enclosure (Ex d IIC T6) and Intrinsic Safety (Ex ia IIC T6).

 Unique sealing techniques, ingress protection rating reaches IP66/IP67.

 Material for wetted part can be selected from 304, 316L, and coating material ECTFE/PTFE.


Float-11 series has two models for various liquids with different chemical properties:

Float-11A Standard: made of 304 or 316L stainless steel, suitable for most of liquids.

Float-11P Coated: With ECTFE/PTFE coating for strong corrosive liquids level measurement.
