MC Anti-corrosion and explosion-proof ultrasonic level meter 4-20MA
Introduction
Ultrasonic level meter is a monitoring instrument for measuring
liquid height, tank height and material position. The instrument itself can adopt two wire system, three wire system
or four wire system technology, two wire system: power supply and
signal output common; Three-wire system: single X power supply loop and signal output
loop, when using DC 24V power supply, can use a 3-core cable, the
negative end of the power supply and the negative end of the signal
output share a core wire; Four-wire system: when the USE of AC 220v power supply, or when the
use of DC 24V power supply, the power supply loop and signal output
loop is completely isolated, should use a 4-core cable. Dc or AC power supply, with 4~20mADC, high and low switching
output.
Specification
Operating principle
Anti-corrosion and explosion-proof ultrasonic level meter is a
digital level meter controlled by microprocessor. In the measurement of ultrasonic pulse from the sensor
(transducer), the sound wave reflected by the surface of the liquid
is received by the same sensor, through the piezoelectric crystal
converted into electrical signals, and the time between the
transmission and reception of the sound wave to calculate the
distance from the sensor to the surface of the liquid to be
measured. Due to the use of non-contact measurement, the measured medium is
almost unlimited, can be widely used in a variety of liquid and
solid material height measurement.
Algorithm optimization, intelligent filtering, high frequency
signal, strong penetration, stable measurement
1. Liquid crystal display liquid level value, measurement data at a
glance
2. The electrical interface is made of ABS material, resistant to
impact and aging
3. Integral seal to prevent dampness from affecting the performance
of the whole machine
Intelligent acoustic wave technology can carry out intelligent echo
analysis, without any debugging and other special steps, this
technology has the function of dynamic thinking, dynamic analysis. The precision of the instrument is greatly improved, the precision
of liquid level reaches 0.5%, and it can resist all kinds of
interference waves.
Performance characteristic
1. Choose high-quality power module, components choose imported high
stability and reliable devices, can completely replace the same
type of imported instruments
2. Acoustic wave intelligent technology software can carry out
intelligent echo analysis, without any debugging and other special
steps, this technology has the function of dynamic thinking and
dynamic analysis
3. The liquid level accuracy is 0.25%, which can resist various
interference waves
4. Range :0-15 meters, various forms of optional, suitable for all
kinds of corrosive, chemical applications, high precision, remote
signal output,PLC system monitoring

Construction
Product dimension drawing
Installation method: bracket installation is generally adopted in open environment. Cut
a round hole with a diameter of 60mm on the installation position
of the tank or tank with the instrument's own flange, put the
instrument probe into it, and then screw the flange upward to
ensure that the probe surface of the instrument is level with the
measured liquid level
B(Blind area): 0.35 m to 0.6 m D: ullage L: level
H:Height F: Distance from the wall(0.3~2m) L:L-D
1. The datum level of measurement is the lower edge of the sensor.
2. The upper limit of object level cannot enter the blind area of
measurement
3. When measuring the material level, it must avoid the feed
opening.
4. It is best to protect against long-term rain when installed
outdoors
Application areas: water and sewage treatment: pump house, water collection well,
biochemical reaction pond, sedimentation pond, etc. [2] Power mine:
ash pond, coal slurry pond, water treatment, etc
