Principle

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.

The ultrasonic velocity in gas is influenced by the gas temperature,So the level meter need to detect the gas temperature at work. So the material level meter need to detect the gas temperature at work,compensation for sound velocity.

Blanking distance: Span F may not extend into the blanking distance B. Level echo from the blanking distance cannot be evaluated due to the transient characteristics of the sensor.

Application
To ensure that the ultrasonic transmission to the measured ultrasonic liquid level or material surface occasion.

Such as: storage tank, chute, pool, Wells, drains, metering box, granary etc.

Features

♦ Integrated design, installed conveniently
♦ Protected in the excessive voltage and current , protected in the thunder and lightning

♦ The big show window of LCD is easy to debug and observe

♦ Over-voltage over-current protection, lightning protection

♦ Advanced since the clamp type terminal, to ensure that wiring never loose

♦ Intellectual signal treatment technology, guarantee that the instrument meets various kinds of operating occasion

♦ All plastic probe, acid and alkali resistant, adapt to bad environment

Range
The instrument has the following range specifications: Liquid level: 4m,6m,8m,12m,20m,30m;

Material level: 3m,5m,7m,10m,15m;

Note

♦ The above range level measurement only,Material level measuring the effective range of about 50% of the data,material level measuring proposal chooses four wire or split type level gauge.

♦ Cold area outdoor installing applications, should prevent the probe surface frost or freeze.Can choose pipe long material level meter, the internal probe into the container,above model and models.
