Freon Refrigeration ultrasonic level meter
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 (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 Installation height H from a user entry, it can calculate the level as follows: L=H-D
An integrated temperature sensor compensates for changes in velocity of sound caused by temperature changes.
power supply:
DC24V ±5%: For four-wire system, and the power supply current should not be less than 80mA.
AC85~265V:Only for four-wire system and the remote version series, and the power supply current should not be less than 50mA
Continuous non-contact level measurement with compact version;
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;Excellent anti-interference capability;4-20mA output;Intellectual signal treatment technology, guarantee that the instrument meets various kinds of operating occasionAll metal outer cover (IP67), airproof and alkali-resisting, meet the abominable environment.
