please verify to factory before ordering 3.For RS485-PC product, users can adjust the parameter by
software(the default software) The max measure range depends on the smooth level surface, so
please confirm the real |
PL320 3meters ultra sonic water level sensor 4-20mA combines
ultrasonic sensors, temperature sensors, ultrasonic servo circuit,
transmission circuit and uses SMD components and ASIC which is developed
together with the United States partner.
All these features realize a concise and smart level transmitter. All gold-plated
circuit boards, internal electromagnetic shielding and software digital filter are tested for (industrial) 48 hour under high and
low temperature aging. It promises higher and long-term reliability. Shell is made of solid texture and good NLEPF acoustic
characteristics of synthetic material. The body is shape sophisticated aesthetics, waterproof, dustproof, and can adapt to
the most of working conditions on site.A very quick and easy installation, maintenance can be realized.
Features
● Range of up to 60 meters
● Level or material measurement
● Level or material measurement
● Response speed is adjustable
● Easy Installation
Applications
● River water level measurement
● Lake water level measurement
● Shallow water level measurement
● Hydrological monitoring
● Environmental protection
Notes for selection range of ultrasonic level sensor:
For example, in a tank for measuring hydrochloric acid level, due
to the strong volatility of the medium, the air in the tank may
suspend a large number of fine liquid particles, which will scatter
part of the sound waves of the ultrasonic level gauge. For this
phenomenon, when the liquid drops to a lower level, the ultrasonic
liquid level gauge may not receive echoes. Therefore, it is
recommended that the user increase the measurement distance by
30-50% when selecting the range. For example, for a 6-meter-high
tank, it is best to use a 10-meter Uson-11 ultrasonic liquid level
gauge for measurement.
