Description
Ultrasonic level meter is an intelligent non-contact liquid (object) level measuring instrument.
Ultrasonic level
meter is composed of three parts: ultrasonic probe, ultrasonic control host.
This meter adopts modular circuit design, high quality multi-layer PCB board, tight hardware structure and
reasonable layout. The product adopts 18-key operation menu, supports isolated 4-20mA output, supports HART
communication, built-in GPRS, GPS, 4G and other wireless data transmission, built-in 500,000 storage, supports
USB storage export, and can also add modules to achieve other functions according to customer needs.
This product can meet most of the requirements of liquid level and material level measurement without
contacting industrial media, and completely solves the shortcomings of winding, blockage, leakage, media
corrosion and inconvenience of maintenance brought by traditional measurement methods such as pressure type,
capacitor type and float type. Therefore, it can be widely used in various fields related to material level, liquid level
and monitoring
 
Product features
Ultrasonic non-contact level measurement, completely no effect on the measured liquid, accurate level
measurement is the ideal level meter.
Low power consumption, easy installation and positioning, it is widely used in petrochemical, metallurgy,
electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and
industries for liquid level measurement of various media.
Ultrasonic level meter with history flow meter recording function, can record the flow data of the past 60
hours, 30 days, 12 months, 10 years, and 500,000 items are stored in the body.
The instrument has a comprehensive control function with four-way relay signal output, which is easy to
connect with common actuators (motor, alarm, etc.).
According to the requirements of working conditions, the probe can be selected from special models such as
IP68, anti-corrosion, explosion-proof, small blind area high-precision type, ultra-low power consumption, large
range, etc.
Chinese display interface, 18-key key operation. More easy to understand menu options, more... Quickly
realize man-machine communication.
Built-in remote communication module, various communication protocols can be customized (customized
when ordering).

  1. Common problems and how to deal with them
Please deal with the malfunction during use as follows.
After treatment, the fault still exists or other phenomena appear, please contact our after-sales service personnel.
 
Serial No.PhenomenonPossible reasonsProcessing method

1

None displayed

Not energized or DC power supply, output load is too large
Check the power connector, check the load, and check whether there is still power for the battery backup

2

Displayed, no measurement data
Signal input not connected Measurement turned off, parameter errorCheck input signal cable Check software settings, system
restore

3

Clock inaccuracy

Not aligned or clock crystal deviation
Go to the administration menu to retune


4

No signal output or abnormal output

Wrong setting of relevant parameters Current load resistance is too large
Check software settings, system restore
Current load resistance should be
<300

5
Serial port communication exception
Wiring error or different settings of master and slave

Check RS485 wiring, check software settings
6Display system errorSetting parameters are missingSystem restore, reset all parameters
7Display input errorError in input dataCheck the data
