The high temperature and high pressure guided wave radar level sensor is specially designed for high temperature and high pressure occasions. The product is mainly used for liquid level measurement on various boiler drums. Has high safety and accuracy. The highest rated pressure reaches 40MPa. The highest rated temperature reaches 400℃. It is suitable for high and low pressure heaters, condensers and deaerators in thermal power plants. As well as for liquid level measurement under high temperature, high pressure, vacuum and other steam conditions.
Features of GWR High Temperature Liquid Level Sensor
- Applicable medium: liquid, especially liquid in high temperature and high pressure environment.
- Application: Sealed tank, high pressure liquid measurement.
- The traditional method is realized by means of balance vessel, differential pressure transmitter and temperature compensation. Because it is an indirect measurement method. Differential pressure transmitters work under high static pressure and small range conditions, and there are many factors that affect the measurement accuracy. Especially when the start or load fluctuations, the entire measurement unit cannot be used The phenomenon of inaccurate operation or measurement. The guided wave radar level gauge (transmitter) will not be affected by those factors. The probe will not be affected by steam condensate. Always maintain extremely high measurement accuracy (0.1%FS).
- Self-guided wave radar technology is a mature application of liquid level measurement under high temperature and high pressure steam conditions. This advanced liquid level measurement technology has outstanding advantages such as accuracy, stability, high precision and long life. It is gradually replacing traditional measurement technology.

Advantages of using guided wave radar level sensors on boilers
Guided wave radar level sensor is often used in industrial production. Because of its superior performance, it is accepted by the public. It has the advantages of low maintenance cost, strong detection performance, accurate measurement accuracy, high safety, and long service life. The signal emitted by the device is not affected by the environment, atmosphere. So it can be used in a variety of special media, such as high temperature, high pressure, steam state, volatile gas, dust, vacuum environment, etc.
Today I want to share with you how to use the guided wave radar level sensor in the boiler. The high temperature and high pressure in the boiler need to use the level sensor to measure the internal liquid level to ensure its safety. The use of guided wave radar level sensors can solve the difficult problems of safety, accurate readings, and simple maintenance.
On some boilers, each boiler installation requires at least two independent water level sensors. Therefore, each boiler also needs to be equipped with two guided wave radar level sensors. Only in this way can the safety requirements for boiler operation be fully met. Guided wave radar level sensors need to use quartz tubes to observe changes in the liquid level in the furnace. However, the connecting pipes and valves need to be opened to improve the accuracy of detection. It is necessary to ensure that the probe and sensor are dry and clean during installation. If contamination occurs, it can not be wiped with a wet towel, and alcohol must be used for decontamination.
Although many cities do not yet have standard regulations on boiler level sensors. At least one intuitive level sensor must be installed, together with a guided wave radar level sensor for observation. If it is a large and complex complete set of boiler equipment, it is necessary to redesign and plan the guided wave radar level sensor and install it according to the design drawing.
If you need to measure river water level, open channel level, etc. The Ultrasonic Liquid Level Sensor can be used for non-contact continuous level monitoring.
Float Type Level Switches
Continuous Level Sensor Series
Continuous level sensors are transmitters that measure liquids within a specified range. Level sensors determine the exact amount of liquid that provides a continuous analog signal. The level signal can be displayed directly on site or integrated into a process control or management system. These products can be installed vertically and horizontally. They are ideal for monitoring liquids in confined or restricted areas.
What are the different types of level sensors?
Common liquid level sensors are:
Float type liquid level sensor, magnetostrictive liquid level sensor,
Capacitive liquid level sensor, resistance liquid level sensor,
Radar level sensor, laser level sensor,
Ultrasonic liquid level sensor, pressure sensor,
Bubble level sensor, isotope level sensor,
Thermodynamic liquid level sensor
Therhere are 7 main types of level transmitters that Sino-Instroffers. Each type of transmitter works in a different way, and makes it useful for different types of processes.
More about level sensors from Wikipedia.
What is a liquid level sensor?
The liquid level sensor is a pressure sensor that measures liquid level. The static pressure input type liquid level transmitter is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses an isolated diffused silicon sensor or a ceramic capacitive pressure sensitive sensor to convert the static pressure into an electrical signal. Temperature compensation and linear correction are converted into standard electrical signals (usually 4～20mA/1～5VDC)
How does a float level sensor work?
Float level sensor: Float level sensor is designed and produced based on the principle of buoyancy and static magnetic field. The position of a floating ball with a magnet (floating ball for short) in the measured medium is affected by buoyancy. The change of the liquid level causes the position of the magnetic float to change. The role of the magnet and sensor (reed switch) in the floating ball changes the number of components (such as fixed resistance) connected in series to the circuit. Thereby changing the electrical quantity of the instrument circuit system. That is, changes in the position of the magnetic float cause changes in the electrical quantity. The change of the electrical quantity is detected to reflect the liquid level in the container.
