Are you currently facing issues with overflowing chemical tanks or inaccurate liquid volume calculations that affect production costs? These problems can be managed with a Tank Level Gauge or high-quality liquid level sensor. The expert engineering team from SCMA is ready to provide consultation, design solutions, and install fully integrated tank level measurement systems. Readers will gain an understanding starting from the operating principles of each type of tank level gauge, maintenance methods, as well as techniques for selecting the right product to meet real-world industrial usage requirements.
What is a Tank Level Gauge?
Tank Level Gauge or tank level gauge is an important device used to measure and monitor the amount of liquid or material inside storage tanks, whether it is water, chemicals, or oil. Installing a tank level measurement instrument helps users accurately know the current liquid level to enhance work safety and effectively reduce production process errors.
Operating Principles of Tank Level Gauge
The operating principles of Tank Level Gauge from SCMA are designed to control liquid levels to prevent overflow through various types of sensors. These technologies range from using radar waves reflected from the liquid surface, measuring pressure from the weight of the liquid, to using a float magnet to send signals to the display panel. Users can choose the operating principle that is suitable for the type of material in the tank.
How Many Types of Tank Level Gauges Are There?
Devices such as Level Sensor or tank level gauges are available in various forms depending on the suitability of the environment. Based on SCMA's experience, we can categorize them mainly as follows:
Radar Level Meter
The radar type is a non-contact measurement technology that emits electromagnetic waves to impact the material surface. This type of tank level gauge is highly suitable for high-temperature liquid storage tanks, corrosive chemicals, or harsh environments.
Ultrasonic Level Transmitter
The ultrasonic type works by emitting high-frequency sound waves to impact the object surface and then receiving the reflected sound to calculate the distance. Level sensor of this type is suitable for general water applications that do not require the device to come into direct contact with the liquid.
Submersible Level Sensor
The submersible type is a tank level measuring device that uses the principle of lowering the sensor into the tank or pit to measure water pressure. This type of equipment is easy to install, space-saving, and suitable for measuring water levels in boreholes, underground water tanks, or wastewater treatment pits.
Float Switch / Sensor
The float type is a system that uses the movement of the float according to the liquid level to operate the magnetic switch. This type of tank level gauge has a simple mechanism, high durability, and is commonly used for controlling water pumps or alerting overflow water levels.
Maintenance of Tank Level Gauge
Regular maintenance of the tank level gauge is crucial to prevent erroneous readings. The maintenance engineering team should conduct inspections according to the type of level measuring instrument as follows
1. Magnetic Level Gauge
This type of device is highly durable but must be careful about dirt clogging. Operators should remove the gauge from the system and detach the bottom flange to clean the measuring chamber. Check that the float moves freely to prevent jamming
2. Tubular / Reflex Level Gauge
The recurring problem is dirt on the glass, making it difficult to see the oil level. The maintenance team should clean the glass with a specialized cleaner. If cracks are found, replace the glass along with new gaskets immediately to prevent leakage
3. Electric and Electronic Level Gauge
For radar or ultrasonic level sensors, regularly clean the sensor head area to prevent fat buildup. Check the signal cables to ensure they are not bent to prevent data transmission failure to the control room
Application of Tank Level Gauge
Tank Level Gauge is a device that enhances safety, prevents tank overflow, and enables accurate inventory management. It is mainly applied in the following industrial sectors
1. Process Control
Factories can use the tank level gauge to monitor the amount of chemicals in mixing tanks in real time. Continuous data transmission helps prevent liquid overflow from the tank, as well as prevent the machine from running empty when the tank is empty
2. Inventory Management
Checking the volume of oil or chemicals in silos is important for calculating remaining quantities. Level sensors help reduce raw material loss due to leakage, enabling accurate purchasing or transportation operations
3. Safety & Environmental
For managing waste water or hazardous chemicals, the tank level gauge reduces the risk of workers coming into direct contact with chemicals. These devices will alert before wastewater overflows the treatment pond, causing environmental problems
Advantages of Tank Level Gauge
The main advantage of Tank Level Gauge is the real-time display of liquid or solid quantities, allowing operators to control stock accurately. The tank level gauge also helps prevent tank overflow problems, increasing work safety. It can withstand extreme environmental conditions such as high pressure or corrosive chemicals very well.
How to Choose Tank Level Gauge
To choose a Tank Level Gauge that is cost-effective and meets usage requirements, it is necessary to primarily consider the on-site environmental factors. The expert team from SCMA recommends the following checklist for selecting Tank Level Sensor:
- Analyze the characteristics of the material to be measured, such as being liquid, solid, corrosive chemicals, or having a lot of dust particles
- Check the temperature and pressure inside the tank to select a tank level gauge material that is durable under actual usage conditions
- Consider the height and shape of the storage tank to assess the sensor signal range coverage
- Determine the desired display format, whether it is viewing values on the tank or sending digital signals back to the control system
- Choose a supplier with expertise, after-sales service, and can provide proper installation consultation for Tank Level Measurement Instruments
Summary
Tank Level Gauge is an important tool for controlling production quality, increasing safety, and preventing damage from chemical tank overflow accidents. If your factory is looking for high-quality level sensors, SCMA is ready to be a partner, providing professional integrated solution design and consultation.
