Due to the particularity of the nuclear power plant, the spent fuel pool and the built-in refueling water tank are not allowed to be perforated at the bottom, and in order to monitor the liquid level change of the spent fuel pool and the built-in refueling water tank of the nuclear power plant, a membrane box liquid level transmitter with a capillary tube is arranged in the spent fuel pool and the built-in refueling water tank, and the membrane box is immersed in the water pool and fixed at the bottom of the pool. The immersion level gauge converts the static pressure into a standard electrical signal based on the principle that the measured hydrostatic pressure is proportional to the measured height, and performs a level measurement. The existing immersion type liquid level meter mounting mode has the problem that the water tank needs to be emptied for verification. Aiming at the problems existing in the installation and verification of the immersion type liquid level meter, a mounting bracket is provided so as to facilitate the installation and verification work of the immersion type liquid level meter.
