Input level transmitter is designed for continuous measurement of liquid level changes, when the submersible level transmitter is put into a certain depth in the measured medium, the pressure of the measured medium is introduced into the positive pressure cavity through the pressure hole of the submersible level transmitter, and then the atmospheric pressure (Po) on the liquid level is connected to the negative pressure cavity of the sensor through the cable air tube to offset the (Po) on the front of the submersible level transmitter, so that the pressure measured by the submersible level transmitter is ρgh, and finally the level depth can be obtained by measuring the pressure P. At the beginning of the design of the pressure hole of the submersible level transmitter, the problem of “blockage” was noted, so the use of a beveled structure can greatly reduce the problem of the pressure hole of the submersible level transmitter being blocked. The bottom slope of the submersible level transmitter has 4 5mm diameter impulse holes, which are generally not all blocked, and the following two solutions can be used in the application scenario of easy to block the medium: First, when the submersible level transmitter is put into the medium, do not directly put it at the bottom of the measured medium, so that the submersible level transmitter probe is suspended, as high as possible above the measurement point that may be buried, so as to effectively prevent the pressure hole of the submersible level transmitter from blocking. Second, insert or install a steel pipe or PVC pipe larger than the diameter of the probe of the submersible level transmitter in the measured medium, and open several small holes with a diameter of about 5mm at different heights in the opposite direction of the medium flow direction (note that the opening point is higher than the measurement point that may be flooded by sediment), so that the medium enters the pipe. Submersible level transmitters increase the service life of submersible level transmitters by measuring in the tube to prevent contact with sediment or media that is easy to block the impulse hole.
