Inhibitors are widely used in many fields such as antibacterial, mildew proof, and disinfection and other ideal antibacterial agents. Biocides control or kill microorganisms, bacteria, fungi and algae in water systems. The main fields are agricultural fungicides and industrial fungicides.
Inhibitors and Biocides are corrosive liquid, and it is important to take level measurement of inhibitors and biocides.
Inhibitors and Biocides level measurement is important
Liquid level measurement has been widely used in petroleum, chemical, meteorological and other industries. The realization of non-contact level measurement and intelligent measurement is the current development direction of liquid level meters. With the research and development of high and new technologies such as computers, microelectronics, and sensors, the development of ultrasonic liquid level instruments has made great progress in recent years, and has been rapidly updated to meet higher and higher application requirements; it is a perfect solution for Inhibitors and Biocides Level measurement.
Non- Contact liquid level measurement
Ultrasonic level sensor is the fastest growing instrument in non-contact level measurement. Ultrasonic level transducer works based on the principle that ultrasonic waves are reflected on the surface of the object to be measured, and the principle that the measured distance is a function of time.
Since the speed (v) at which ultrasound travels through a specific medium is known (e.g., in air, it is affected by temperature, but this is usually compensated for), the distance (D) from the sensor to the liquid surface can be calculated by measuring the total round-trip time (T) of the ultrasonic pulse. The calculation formula is:
D = (v × T) / 2
Where:
Once the distance (D) is determined, the liquid level height (L) can be easily calculated using the known installation distance (H) from the sensor to the bottom of the tank:
L = H - D
This unit amplifies, filters, and identifies the weak received echo signal to precisely determine the echo's arrival time.
The instrument also performs temperature compensation and other processing to enhance measurement accuracy and stability.
Modern ultrasonic level transmitters often offer multiple output interfaces, such as:
o Level meter with 4-20 mA analog signal
o Digital signals (e.g., HART, Modbus,Profibuds)
These interfaces enable easy integration of the level data into control systems or monitoring platforms.
Ultrasonic liquid level transmitters are used in the water level measurement of rivers, lakes, water, canals and other water bodies, as well as in the liquid level measurement of oil, slurry and other liquids. Ultrasonic liquid level measurement technology plays an important role in more and more fields. Ultrasonic level transmitter for inhibitors and biocides has the characteristics of advanced technology, high measurement accuracy, wide measurement range and good long-term operation stability, and is favored by many customers. The maximum range of SILVER HL series ultrasonic level sensor is 40m, and its accuracy is as high as 0.2% of the range, which is very high precision ultrasonic level sensor. At the same time, Ultrasonic level sensor and transmitter supports 4~20mA two-wire or four-wire power supply.
Ultrasonic level meter for water, river, chemical measurement
Many Inhibitors and Biocide ultrasonic level sensors use digital interfaces to easily provide the signals required for telemetry and remote control, especially with various fieldbus interfaces which can be easily connected to the entire automation management system. Such as HART communication protocol, MODBUS RS485, PROFIBUS DP communication protocol, so that users can obtain ultrasonic liquid level measurement information from many places, obtain timing Inhibitors and Biocides level and volume information, and achieve ideal online control. This is an intelligent integrated non-contact continuous level measuring instrument suitable for various process control systems, which represents the development direction of liquid level measuring instruments.

HL series ultrasonic liquid level measuring instrument has a variety of wetted material options, such as ABS ,Teflon or PVDF material, which can measure corrosive liquids, such as pesticides, inhibitors and Biocides.
PVDF or Teflon level sensor material for corrosive liquid
The intelligent ultrasonic level meter can accurately process and analyze the received signal: non contact ultrasonic level sensor can filter out various interference signals from Inhibitors and Biocides tanks, identify multiple echoes, and analyze the signal strength and ambient temperature and other related information. This enables accurate measurements even in the presence of external disturbances.
With the patented technology of ultrasonic intelligent signal processing and extremely high signal-to-noise ratio indicators, non contact ultrasonic level sensor has the automatic false echo suppression function to eliminate the interference of fixed obstacles, which effectively avoids the influence of fixed obstacles on the measurement.
Due to the diversification of the measurement objects of the ultrasonic level sensor, such as industrial wastewater, bleaching liquid, resin and various solutions, and the harsh environment (high temperature, noise, moisture, etc.), high-quality ultrasonic level sensors with robust construction to meet the demand. We have plastic and aluminum shell materials to choose from.
