Model HS-200 -High Precision Top- Mounted Ultrasonic Level Meter

1. The distance of transducer launching surface to the lowest level should be less than the purchase instrument range
2. The distance of the transducer launching surface to the highest liquid level should be greater than the purchase of the blind instrument
3. The launch surface of the transducer should be keep parallel to the liquid surface. 
4. Transducer installation location should be as far as possible avoid these liquid surface fluctuations position that just under the inlet, outlet ,if It is impossible to avoid,please install guided-wave tube to aid in measuring.
5. If the pool wall or tank wall is not smooth, meter installation location should at least more than 0.5m from the pool wall or tank wall. The specific distance from the pool wall or the tank wall determined according to the actual situation.
6. If the distance of the transducer launching surface to the highest level is less than the blind area of the purchase instrument is required to install an extension tube, that diameter is greater than 200mm, and the length is 0.35m~0.50m.

• Measuring range : 0~10m(Chosen based on actual measuring range)
• Blind area : 0.3m~0.6m
• Ranging accuracy : 0.3% (Standard condition)
• Ranging resolution  : 1mm
• Pressure : less than two atmospheric pressure
• Meter display : With LCD to display liquid level
• Analog output : 4~20mA
• Digital output : RS485, Agreement Modbus or customization agreement
• Power supply voltage : DC24V/AC220V, lightningproof device installed inside
• Ambient temperature  : -20℃ ~ +60℃
• Protection grade : IP65

The meter is with following features:

1. For circuit design, high-quality power modules are selected to be as power supply parts, highly stable and reliably devices are used as components;
2. Patent sonic-wave intelligent technology software can make intelligentized echo analysis. It needs neither debugging nor other special steps. This technology has functions of dynamic thinking and dynamic analysis
3. Our sonic-wave intelligent patent technology greatly improves the meter’s precision up to 0.3%, which is enough to resist various interference waves;
4. Non-contact and does not directly contact liquid, so the fault rate is low. The meter can be installed in several different ways, and the user can make meter calibration according to the Manual;

All input and output lines must be with such protection functions as lightning protection and short circuit prevention.
