CS-2000Intelligent external mounted ultrasonic level gauge
1Product Overview
CS-2000Intelligent external mounted ultrasonic level gauge,It is a new technology and product developed by our company. The liquid level measurement adopts a sensor external attachment and non-contact measurement method with the measured liquid, which is a major innovation in the history of liquid level measurement.CS-2000Intelligent external ultrasonic level gauge can continuously measure the liquid level outside the tank without opening holes or stopping production during installation, especially suitable for the replacement of old products.CS-2000The intelligent external mounted ultrasonic level gauge is particularly suitable for precise measurement of various toxic substances, strong acids, strong alkalis, and pure liquids in sealed containers. The instrument adopts explosion-proof design and can also be applied in situations where explosion prevention is required.
2Working principle
CS-2000The external mounted ultrasonic level gauge adopts the principle of radar echo ranging, combined with the company's digital signal processing technology, to overcome the influence of tank walls and achieve high-precision non-contact measurement of the liquid level inside the tank. The instrument uses our company's independently developed specialized ultrasonic processing technology as the system core, achieving ultra high speed digital signal processing functions. The processed liquid level height value is accurate and does not requireCPUFurther analysis, comparison, and judgment.CPUAfter obtaining the liquid level value, it can be sentNVRAMStore and send digital displays for display. In addition, the instrument can output4~20mAStandard signal or throughRS-485The interface outputs the measurement results to the upper computer (or secondary table).

5Application conditions
5.1 Purity of the medium
● Liquid cannot be filled with dense bubbles.
● Large amounts of solids, such as crystals, cannot be suspended in liquids.
● Large amounts of sediment cannot be deposited in liquids.
5.2 Viscosity
● Dynamic viscosity<10mPaoS.10mpaS<Dynamic viscosity<30mPaSThis may reduce the instrument range. Dynamic viscosity>30mPaSTime cannot be measured. Note: As the temperature increases, the viscosity decreases, and most high viscosity liquids are more affected by temperature. Therefore, when measuring liquids with viscosity, attention should be paid to the influence of liquid temperature.
5.3 Tested container
● Material: The container wall where the measuring probe is installed should be made of a hard material that can transmit signals well. For example, materials such as carbon steel, stainless steel, various hard metals, fiberglass, epoxy resin, hard plastics, ceramics, glass, hard rubber, or their composite materials. If the container wall where the measuring probe is installed is made of multiple layers of material, the layers should be in close contact without bubbles or gas interlayers, and the inner and outer surfaces of the container wall should be flat. Examples: vulcanized hard rubber lining, epoxy resin lining, stainless steel lining, titanium lining.
● Wall thickness:2~70mm
● Tank types: spherical tank, horizontal tank, tank, vertical tank, etc.
5.4 Probe installation requirements
● For iron containers, the working end face of the probe can be coated with silicone grease and directly attached to the bottom of the container with a magnetic suction cup; If the container shell is made of glass or other materials, the probe can be glued and fixed with glue or fixed to the bottom of the container with a bracket. The probe point must be on the same straight line as the measured distance.
● There are no obstructions such as coils directly above the probe;
● Stay away from the bottom inlet of the tank to avoid the impact of severe liquid flow on the measurement;
● Stay away from the position below the top of the tank and the liquid inlet to avoid the impact of the liquid inlet, which may cause severe fluctuations in the liquid level and affect the measurement;
● Above the liquid outlet or sewage outlet to avoid long-term accumulation of pollutants at the bottom of the tank, which may have adverse effects on the measurement. If the conditions are not met, measures should be taken to ensure regular removal of dirt from the bottom of the tank;
● Magnetic or welded liquid level measuring head/When installing with adhesive fixation method, the installation surface size on the container wall should not be less than Ø100mmThe surface roughness of the circular surface should reach1.6The inclination should be less than3°(Excluding bypass pipes).

10Installation method
● Installation diagram of ordinary type (single probe)
● Installation diagram of self calibration type (dual probe) The calibration probe provides temperature and pressure compensation for the measuring probe, enabling the main probe to timely and accurately correct measurement errors caused by temperature and pressure during measurement, ensuring high-precision liquid level measurement of the instrument in complex environments. There are several ways to install calibration probes:
● ① The diameter direction position of spherical tanks, horizontal tanks, and vertical tanks;
● ② The bottom of the processed calibration plate;
● ③ A pipe or blind pipe with a larger diameter and filled with liquid connected to the tank body. For example, discharge pipes filled with liquid, feed pipes, etc. But the wall thickness8mmThe diameter distance of the pipe needs to be within0.15mabove; wall thickness10mmThe diameter of the tube needs to be0.2mabove; wall thickness15mmThe tube has a diameter of0.25mabove; And so on.
Note: Please consult with the manufacturer for the selection or specific installation plan.
