Products Description
Need precise, real-time level monitoring for your tanks, vessels, or silos? Guanjiang's Level Gauges are precision instruments designed for measuring and monitoring liquid or solid levels across industrial applications. These devices provide real-time visibility into container content levels, enabling precise inventory management and process control while ensuring operational safety and efficiency. Available in multiple technologies — magnetic, glass, radar, ultrasonic, and capacitance types — they offer solutions for different media characteristics and operational requirements, from simple visual indicators to sophisticated electronic transmitters.

Frequently Asked Questions
Q1: Which level gauge technology is best for my application?
A: Magnetic — local visual indication, no power, high pressure/temperature, hazardous areas. Radar — continuous 4-20mA, unaffected by dust/vapor, for liquids and solids. Ultrasonic — non-contact, cost-effective, easy installation. Capacitance — point level detection, high temperature/pressure. Glass — direct visual, low pressure, low temperature. Contact us with your application details for a recommendation.
Q2: Can the level gauge be used with corrosive or high-purity media?
A: Yes. We offer wetted materials in Hastelloy, PTFE, and 316L stainless steel for corrosive environments. For food/pharmaceutical applications, sanitary designs with Tri-Clamp connections and electropolished surfaces are available. Please specify your media and hygiene requirements when ordering.
Q3: What output signals are available for integration with control systems?
A: We offer 4-20mA analog output (2-wire loop-powered), HART communication, Modbus RTU (RS485), and relay contacts for alarm points. Digital displays with local indication are also available. Specify your control system requirements for compatibility.
Q4: Are explosion-proof versions available for hazardous areas?
A: Yes. We offer ATEX, IECEx, and CSA certified level gauges for hazardous areas (gas and dust). Explosion-proof housings, intrinsically safe versions, and non-incendive options are available. Please specify your zone classification when ordering.
Q5: What is the typical installation process?
A: Magnetic/glass gauges: Flanged or threaded connection to tank nozzles — install isolation valves for maintenance. Radar/ultrasonic sensors: Top-mounted via flange or threaded connection — ensure clear beam path. Capacitance switches: Side or top mounted via threaded connection. We provide installation drawings and technical support. Factory calibration before shipment is standard.
