Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of magnetic float type level gauge in China. Welcome to buy high quality magnetic float type level gauge at competitive price from our factory. We also accept customized orders.
The HNL90-A magnetic float type level gauge is a robust, reliable measurement device engineered for liquid level monitoring in medium and large tanks, ideal for industries like petrochemical, wastewater treatment, marine engineering, food processing, and chemical pharmaceuticals. Operating on the magnetic float principle, it features a bypass tube with an internal magnet-equipped float-when the liquid level rises or falls, the float attracts the opposite-pole magnetic flip columns outside the tube, switching their color from white to red for clear, real-time visual indication, no external power required.
Crafted with corrosion-resistant materials (304/316 stainless steel, UPVC, or PTFE lining), this level gauge handles corrosive, flammable, toxic, high-temperature (-160℃ to 450℃), and agitated liquids, with a maximum working pressure of 100bar. It offers a wide measurement range (150-7000mm) and flexible precision options: standard <±10mm repeatability or optional magnetostrictive technology for <±1mm accuracy and <5ms response time. Equipped with IP65 protection (IP68 optional) and Exd IICT5 explosion-proof certification, it ensures safety in harsh and hazardous environments.
Versatile in functionality, it supports 4-20mA analog output, HART protocol, and switch signal outputs for remote monitoring and control, with customizable upper/lower limit alarms. Its modular design enables easy installation via DN15-DN100 flange connections, and the bypass tube is fully isolated from the flip-column display to prevent contamination.
The HNL90-A magnetic float type level gauge combines durable construction, intuitive visual indication, and industrial-grade adaptability-making it a trusted choice for businesses seeking low-maintenance, reliable level measurement in critical processes, from corrosive chemical storage to food-safe production.

Measurement Principle |
The HNL90-A magnetic float level gauge is installed on the extension pipe on the outside of the tank. The liquid level inside the tank can be clearly seen from the float indicator. A magnetic switch can also be installed on the outside of the bypass pipe as an electrical contact signal output, or a level transmitter can be installed for long-distance liquid level signal transmission and liquid level control. An extension pipe is installed on the outside of the tank, and a level indicator is installed on the outside of the bypass pipe. A float containing a magnet is placed in the bypass pipe. Because the magnetic color plate contains a magnet with the opposite magnetism to the float, when the float rises, it will attract the magnetic color plate, causing the color of the magnetic color plate to flip from white to red, indicating the actual liquid level height. |
