ultrasonic level measuring instrument, taking the advantages of various many level measuring instruments, is a universal one characterized by total digitalized and humanized design. It has perfect level monitoring, data transmission and man-machine communication.
It is featured by strong anti-interference performance; free setting of upper and lower limits and online output regulation, on-site indication, optional analog, switching value, and RS485 output and easy connection with main unit. The cover, made of waterproof engineering plastics, is small and firm with ABS probe. Therefore, it is applicable for various fields concerning level measuring and monitoring. According to the practical situation, it also can add other modules, such as RS 485, current output; it can be match with PLC better.
Features
|
Sensor: Low power consumption, easy to install and locate, standard 4-20mA output, can be using as level gauge alone. |
|
The probe can be made for IP68, anti-corrosion, explosion, small blind, low power consumption, large range |
|
16 key operation. The human-machine communication between can be more efficient. |
|
Backup and recovery parameter set. |
|
Measure for level, volume, weight. |
|
Set a filter value to remove |
|
Output HART, it can be directly communication with other instruments. (Optional) |
|
Mini SD data collection and GPRS communication are optional. |
Ultrasonic level meter adopt ultrasonic theory that sonic wave come across barrier then reflect to transducer, according to the time and speed, distance from barrier and transducer can be got. Measurement formula as below:
D = V * T / 2
D: Measure Distance
V: Speed of sound in air
T: Time of sound in air
