Ultrasonic Level Sensor

Description

The sensor of the meter pulses in the direction of the product surface. There, they are reflected back and received by the sensor.The meter measures the time t between pulse transmission and reception. The meter uses the time t (and the velocity of sound) to calculate the distance D between the sensor membrane and the product surface:

D = c *t/2. As the device knows the empty distance H from a user entry, it can calculate the level as follows: L= H – D

B:Blanking distance D:distance value L:level value

H: installation height F:level span

Two Working Mode

The instrument has two working mode: running state and operating state.

Press the two keys SEL and MOV to change within two different modes.

In running mode, green lamp will keep on lighting. In programming mode, green lamp will flash.

On measuring mode, level meter will carry out normal measuring, at this time, press the SEL key, displayed location value, empty value and temperature will be alternated.

 

Instrument installation

Reasonable instrument installation is the key to its reliable work.

Level meter installed on the top of the container,Probe surface vertical point to liquid level. If is airtight container,should be adopted flange installation.Other conditions can use bracket installation.

Flange installation should be according to the thread sizes make the flange of the level meter.20m,30m type has directly equipped with the flange.

General Instruction

1. The temperature of the process may not exceed 75℃,and the pressure may not exceed ±0.1 MPa.

2. For exposed or sunny locations a protective hood is recommended.

3.Level meter must be some distance from the tank wall.

4.There’s beam angle when Energy transducer radiate ultrasonic pulse. From energy transducer lower edge to measured medium,please avoid A.B obstacle in the radiation region of ultrasonic wave beam.(For example:human ladder;level switch etc).

5.Please make sure ultrasonic beam angle can not intersect with feed stream.

6.Please make sure the max material level can not enter into measuring blind area.

7.Please try to make sure the energy transducer radiate direction vertical to the medium level.
