ZY-SCS-YWJ-WT Handheld External Ultrasonic Liquid Level Gauge
One product overview
When measuring with a handheld external ultrasonic level gauge, the ultrasonic probe is installed directly below (at the bottom) the outer wall of the container being measured, without the need for holes. It is easy to install and does not affect the site. It can measure various toxic substances and pure liquids in high-temperature and high-pressure sealed containers. The instrument adopts explosion-proof design to meet explosion-proof requirements.
II Instrument characteristics
☆ External probe, no need to open holes in the tested container, achieving non-contact measurement, suitable for various sealed containers that are toxic, volatile, flammable, and easy to handle
Measurement of liquid level in explosive, highly corrosive and other liquid media. The instrument has no mechanical moving parts and a long lifespan. Non corrosive and widely applicable.
The instrument is equipped with ASIC (Intelligent Ultrasonic Specific Hardware Integrated Circuit), which makes the instrument small in size, stable and reliable in measurement results, and suitable for various tested liquids and containers. It is easy to install on site and does not require complex on-site calibration. The instrument is equipped with various calibration functions such as automatic temperature correction and automatic fixed distance calibration, making the measurement results more accurate and reliable. The instrument has complete functions, including RS485 output, 4-20mA output, and switch output.

Five Application conditions
Purity of the medium
Liquid cannot be filled with dense bubbles.
Large amounts of solids, such as crystals, cannot be suspended in liquids.
The bottom of the container should not deposit a large amount of sediment and sand.
Viscosity
Measure normally when the dynamic viscosity is less than 10mPaS. When 10mPaS<dynamic viscosity<30mPaS, the instrument range may decrease. When the dynamic viscosity is greater than 30mPaS, it 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.
Tested container
1. 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, hard plastics, ceramics, glass, hard rubber, or their composite materials. If the container wall at the installation of the measuring probe is made of multiple layers of material, the layers should be in close contact without bubbles or gas interlayers The inner and outer surfaces of the container wall should be smooth Examples: vulcanized hard rubber lining, stainless steel lining, titanium lining.
2. Wall thickness: 2-70mm
3. Tank types: spherical tank, horizontal tank, vertical tank, etc.
Probe installation requirements
1. 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.
2. There are no obstructions such as coils directly above the probe;
3. Stay away from the bottom inlet of the tank to avoid the impact of severe liquid flow on the measurement;
4. 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;
5. Higher than the outlet or drain to avoid the long-term accumulation of dirt at the bottom of the tank affecting the measurement If the conditions are not met, measures should be taken to ensure regular removal of dirt from the bottom of the tank; 6. When the liquid level measuring head is installed by magnetic or welding/adhesive fixation, the installation surface size on the container wall should not be less than a circular surface of Ø 80, the surface roughness should reach 1.6, and the inclination should be less than 3 ° (except for bypass pipes).
