How Hongguang Magnetic Level Gauge Works in Food Processing
The Hongguang magnetic level gauge is widely used for visible and reliable liquid level indication in closed and pressurized vessels. It consists of a float containing a permanent magnet that rises and falls with the liquid. As the float moves, it actuates a magnetic indicator strip or follower outside the chamber, allowing non-contact level observation. In food processing, its hermetically sealed construction prevents contamination and facilitates easy cleaning, meeting hygiene standards. The magnetic level gauge is ideal for monitoring brine, oil, and other process fluids.
Ultrasonic Level Transmitter for Non-Contact Measurement by Hongguang
Hongguang ultrasonic level transmitters provide non-contact, continuous liquid level measurement. The device emits ultrasonic pulses from the transducer, which reflect off the liquid surface and return to the sensor. By calculating the time-of-flight, the level transmitter determines the exact liquid height. This method is particularly valuable for viscous, corrosive, or high-purity applications (e.g., fruit juice, dairy products, syrups), as it eliminates contamination risk and minimizes maintenance.
Radar Level Sensor from Hongguang – Advanced Non-Contact Solution
For challenging food processing environments, the Hongguang radar level sensor uses microwave radar pulses for precise, non-contact level measurement, even under pressure or in the presence of vapor, foam, or turbulence. Radar level sensors are suitable for tanks storing sauces, creams, and other food ingredients with variable dielectric properties. Their high accuracy and resistance to process conditions make them a top choice for critical level monitoring.
Glass Level Gauge and Its Role in Direct Level Indication
The Hongguang glass level gauge offers a simple yet effective means to visually monitor liquid levels in tanks and vessels. It consists of a toughened glass tube or plate fixed to the tank, allowing operators to directly observe liquid height. The glass level gauge is favored in applications where process fluids are not hazardous and visual verification is required, such as ingredient mixing tanks and open reservoirs in food processing plants.
Float Level Switch and Capacitance Level Sensor for Point Level Detection
A float level switch from Hongguang is a mechanical device that opens or closes an electrical contact as the liquid level rises or falls. It is reliable for triggering alarms or controlling pumps at specific setpoints (e.g., maintaining water level in pasteurizers). Capacitance level sensors, on the other hand, detect changes in capacitance caused by the presence or absence of liquid between sensor probes. These sensors are excellent for point level detection in conductive and non-conductive food liquids, providing versatility for different recipes and processes.
Magnetostrictive Level Transmitter for High Accuracy Monitoring
The Hongguang magnetostrictive level transmitter is designed for applications requiring both high accuracy and reliability. It uses a magnetostrictive waveguide and a float containing a magnet. When a current pulse is sent through the waveguide, it interacts with the float’s magnetic field, creating a torsional wave that travels back to a sensor. The transmitter calculates level based on the time taken for the wave to return. Its high precision makes it ideal for batching, blending, and dosing systems in food processing.
Hydrostatic Level Transmitter for Submersible Applications
Hongguang hydrostatic level transmitters measure liquid level by detecting the pressure exerted by the liquid column above the sensor. This transmitter can be installed inside tanks or wells and is particularly suitable for open tanks, sumps, and silos containing water, milk, or other food liquids. Its robust, corrosion-resistant construction ensures long service life and reliability in harsh process environments.
Level Indicator and Level Switch: Real-Time Visual and Electrical Feedback
Level indicators from Hongguang provide real-time visual feedback of liquid levels, which can be combined with level switches for automated control. Level switches are designed to trigger alarms, start or stop pumps, and execute control logic at predefined levels, supporting automated control systems in CIP (clean-in-place), ingredient dosing, and liquid transfer operations.
Level Controller – Integration into Food Processing Automation
The Hongguang level controller acts as the central unit for integrating multiple level instruments and automating liquid handling. It accepts signals from level gauges, transmitters, and switches, processes the data, and outputs control commands to valves, pumps, and alarms. Level controllers ensure optimal tank filling, prevent overflow, support batch processing, and improve overall process efficiency in food plants.
Liquid Level Meter and Tank Level Gauge for Inventory Management
Hongguang liquid level meters and tank level gauges enable accurate inventory management by providing precise readings of storage tank contents. This is crucial for raw material logistics, recipe formulation, and production planning in food processing. The rugged design ensures operation in both indoor and outdoor installations, under varying temperature and humidity conditions.
