The split-type ultrasonic level gauge is a reliable and efficient solution for measuring liquid levels in various industrial applications. It offers advantages such as safety, cleanliness, high accuracy, long service life, and stable performance. Its robust design makes it ideal for use in environments with acidic, alkaline, or corrosive substances, as well as in high-temperature conditions. The device provides real-time level data, making it an essential tool for automation systems across industries like chemical processing, water treatment, food production, and more.
When installing a split-type ultrasonic level gauge, several important precautions should be taken to ensure optimal performance and longevity:
1. Ensure the instrument is properly grounded by connecting the 4-20 mA output or XPS terminal to a reliable earth connection.
2. Protect all wiring and cables using sealed conduits to prevent water ingress, which can damage the system.
3. Although the level gauge includes built-in lightning protection, additional surge protection devices are recommended in areas prone to frequent lightning strikes.
4. In extreme temperature environments, consider adding thermal insulation or heating/cooling systems around the gauge to maintain operational stability.
Proper installation is crucial for accurate measurements. Follow these key principles:
1. The distance from the probe’s emitting surface to the lowest liquid level must be within the instrument’s measurement range.
2. The distance to the highest liquid level should exceed the blind zone of the device to avoid signal interference.
3. The probe’s emitting surface should be parallel to the liquid surface for consistent and accurate readings.
Capacitive level gauges, such as the JZ-ORB model, are widely used for continuous level monitoring in tanks, silos, and hoppers containing liquids or bulk solids. These instruments are known for their reliability in harsh environments and have been successfully implemented in sectors like oil and gas, power generation, food processing, and more.
Key technical specifications include:
- Power supply: 12–36 V DC
- Input range: 10–4000 pF
- Output signal: 4–20 mA (two-wire system)
- Accuracy: ±0.5% of full scale
- Operating temperature: -20°C to +80°C
The sensor (probe) comes in various forms, including rigid and flexible designs, insulated and bare probes, and different mounting options such as threaded or flanged connections. The choice of probe depends on the medium being measured, container type, and environmental conditions.
When selecting or using a capacitive level gauge, consider the following:
a) Match the instrument to the process conditions, including temperature, pressure, and material compatibility.
b) The dielectric constant of the medium directly affects sensitivity. For low dielectric constants (<5 μs/cm), a coaxial sleeve probe is recommended.
c) Grounding the transmitter housing to the vessel is critical, especially for non-conductive containers. A metal rod or coaxial sleeve may be needed for proper grounding.
d) On-site calibration is necessary to ensure accuracy, especially when adjustments are required.
e) Conductive media on the probe can cause false readings, unlike non-conductive materials.
f) For non-conductive media, ensure a stable dielectric constant. Changes due to moisture, temperature, or mixing can affect accuracy and require recalibration.
g) Avoid cutting the insulated electrode; measure and order it correctly before installation.
h) If the medium temperature exceeds 100°C, specify this during ordering to ensure the correct model is selected.
By following these guidelines, you can maximize the performance and lifespan of your level measurement equipment, ensuring accurate and reliable operation in even the most challenging environments.
