CNPS-ML11 Mud Logging Fluid Level Sensor

the cnps-ml11 type drilling fluid volume sensor is an ultrasonic liquid level sensor which combines the sensing technology and the electrical signal processing. It is used to monitor the change of the volume of the drilling fluid.

the cnps-ml11 type drilling fluid volume sensor is composed of an ultrasonic transmitter, a receiving device and a transmitter. The ultrasonic wave emitted by the ultrasonic transmitting device is reflected by the surface of the object, and then is received by the receiving device. The transmitter converts the signal generated during ultrasonic emission and reception to the standard current signal.

the probe of the sensor sends out a series of ultrasonic pulses, while the ultrasonic pulse returns after receiving the liquid level, and is received by the sensor. The filtering device in the sensor can distinguish true echoes from the liquid surface from various false echoes from sound waves, wave noise and rotating agitator blade noise. The pulse wave is converted from the time of temperature compensation to the time used by the emission to the liquid surface and then back to the sensor.
