Ultrasonic Level Meter
LT-200
Key Features
- Degree: 0.2% F.S Resolution: 1mm
- Indication unit selectable by meter, centimeter, or %
- Current value identifiable on display without tester
- Temperature sensor built in detector or converter for automatic temperature correction
- Level change ranging from 5 minute to 48 hours identifiable on display with a built-in trend
- Transmission status identifiable on display with a built-in oscilloscope
- "?" shown on the display for measuring disability or converter error
- Product defect identifiable with current output
- Function to save measured data(micro SD card)
Major Functions
- Liquid crystal display (LCD) for indication of measuring status including Level, Echo, Trend, Temp, %, Bargraph
- Advanced sensor the material of which is suited to tank with corrosive or viscous gas or steam occurs
- Easier level identification in darkness with built-in backlight
- 2 Sensors connected to 1 converter
- Our product made its surface of sensor in rounded form to swiftly help the dew concentrated around () the surface of sensor to fall automatically. Any potential error by dew condensation is completely resolved by 5 times of surface vibration per second that quickly vaporize water molecules.
How It Works
This ultrasonic level meter consists of sensors, a converter, and a dedicated cable. Ultrasonic pulses emitted from the sensors are reflected off the measured liquid and received. The received pulse echoes are inputted as electric signals in the converter by measuring the time difference between the sent and received pulses and outputting signals that are proportional to the distance.
