12VDC Portable Wall Mounted Water Flowmete Ultrasonic Doppler Type Flow Meter Price
Ultrasonic liquid level gauge is a kind of liquid level instrument that uses the ultrasonic principle to measure liquid level. How does the ultrasonic liquid level gauge work? What is the principle of ultrasonic level gauge?
The working principle of ultrasonic liquid level gauge is to
transmit energy wave through ⼀ devices that can transmit energy
wave (⼀ generally pulse signal). The energy wave is reflected by
obstacles, and the reflected signal is received by ⼀ receiving
devices.
The change of liquid (material) level is determined according to
the time difference of measuring the movement process of energy
wave. The microwave signal is processed by the electric device and
finally transformed into the electrical signal related to the
liquid level.
The secondary probe transmits ultrasonic pulse signal to the
measured medium meter. The ultrasonic wave is reflected after
encountering the measured medium (obstacle) during transmission,
and the reflected ultrasonic signal is detected by the electric
module.
Through special software to process, analyze the time difference
between transmitting ultrasonic wave and echo. Combined with the
propagation speed of ultrasonic wave, the propagation distance of
ultrasonic wave can be accurately calculated, and the inlet can
reflect the situation of liquid level.
Features of ultrasonic level gauge
Multi pulse low-voltage multi-point transmitting circuit, double
balance noise suppression multi-point receiving circuit (qf-9000
Series): improve the reliability of the instrument, solve the
problem of inaccurate measurement of uneven material level, and
strengthen the anti-interference energy. It can stably make dynamic
power adjustment, gain control and temperature compensation near
the transmitting tower of the substation.
Advanced detection technology and rich software functions adapt to
various complex environments.
Adopt new waveform calculation technology to improve the
measurement accuracy of the instrument.
It has the function of suppressing disturbing echo to ensure the
authenticity of measured data.
16 bit D / a conversion to improve the accuracy and resolution of
current output.
The sensor is made of Teflon, which can be used in various
corrosive occasions.
Various output forms: programmable relay output, high precision
4-20mA current output, RS-485 digital communication output, split
ultrasonic liquid level probe

Integrated installation principle of ultrasonic level gauge
1.The distance from the emitting surface of the sensor to the
lowest liquid level should be less than the measuring range of the
selected instrument.
2.The distance from the emitting surface of the sensor to the
highest liquid level should be greater than the blind zone of the
selection and purchase of the instrument.
3.The emitting surface of the sensor should be parallel to the
liquid surface.
4.The installation position of the sensor should avoid the
fluctuation of the liquid level as much as possible, such as the
water inlet and outlet.
5.If the pool or tank wall is not smooth, the instrument should
keep the pool or tank wall above 0.3m.
6.If the distance from the transmitter surface of the sensor to the
highest liquid level is less than the blind zone of the selected
instrument, a telescopic tube should be installed, the diameter of
which is greater than 120 mm, the length is 0.35m ≤ 0.50m, the
vertical installation, the inner wall is smooth, and the inner hole
of the tank should be Greater than the inner diameter of the
extension tube. Or the pipe can be directly connected to the bottom
of the tank, the pipe diameter is greater than 80 mm, and the hole
at the bottom of the pipe can easily flow into liquid.
