How does level measurement work in larger tanks?
Level measurement in larger tanks is a critical function for monitoring and controlling liquid levels in industrial processes. Process Surplus offers new and used stainless steel tanks with integrated level gauges in AISI 304 and AISI 316, in volumes from 100-250 000 liters. Level measurement can be done by various techniques, such as float, pressure transducer, radar or ultrasound, allowing precise control of filling, storage and dosing. This is crucial for production in the food, chemical, pharmaceutical and water treatment industries where the correct level ensures product quality and safe operation.
Function and structure
Level gauges are installed on the inside or outside of the tank and are connected to indicators, PLC systems or SCADA for real-time monitoring. They can be fixed, movable or non-contact depending on the characteristics of the liquid and the dimensions of the tank. In larger tanks, multiple sensors are often used for redundancy and accurate measurement over the entire volume.
Materials and construction
Level gauges and associated fittings are manufactured in AISI 304 or 316 stainless steel, with gaskets and seals adapted to pressure, temperature and chemical influences. The design is corrosion resistant and hygienic to reduce the risk of contamination of the liquid.
Pressurized and atmospheric solutions
Level measurement can be used in both atmospheric and pressurized tanks. In pressurized systems, radar or pressure sensors are often used to measure level without opening the tank. Float-based and non-contact sensors are common in atmospheric tanks where pressure and temperature are lower.
Applications in industry
- Food production for precise dosing and filling of ingredients.
- Chemical industry for monitoring acids, bases and saline solutions.
- Pharmaceutical production where the right level is crucial for quality.
- Water treatment and storage of liquids that require constant level control.
- Industrial processes where overfilling or idling can cause downtime.
Technical options and equipment
- Float-based sensors for level measurement in different types of liquids.
- Pressure transducers (hydrostatic level measurement) for both atmospheric and pressurized tanks.
- Radar and ultrasonic transducers for contactless level measurement.
- Multipoint sensors for larger tanks and redundancy.
- Integration with PLC, SCADA or remote monitoring.
- Alarms and automatic control systems for overfill and low level.
Volumes and capacity
Level measurement in tanks can be adapted for a wide range of volumes, from around 100 liters up to 250 000 liters. The choice of measurement technique depends on several factors, such as the size of the tank, the density of the liquid, temperature and chemical properties.
For larger tanks, more advanced solutions, such as multi-point measurement, may be required to achieve more accurate level control. Process surpluses can provide information on the tank design and conditions as a basis for choosing a suitable solution.
