Abstract

The present invention discloses a high-protection-level ultrasonic flowmeter housing and an ultrasonic water meter. The high-protection-level ultrasonic flowmeter housing is composed of an inner housing and an outer housing. The inner housing is a glue potting box for encapsulating circuit boards. The glue potting box is assembled from an upper cover and a lower box body of the glue potting box. The upper cover and the lower box body of the glue potting box are combined to form an inner cavity for installing electronic components and filling sealant. The upper cover of the glue potting box is provided with at least two glue injection exhaust structures. The glue injection exhaust structure includes: a bottom plate, a glue injection exhaust hole penetrating the bottom plate, and at least one layer of wall structure arranged on the top surface of the bottom plate around the periphery of the glue injection exhaust hole, and the height of the wall structure is higher than the height of the glue injection exhaust structure. The base meter of the ultrasonic water meter adopts the above-mentioned high-protection-level ultrasonic flowmeter housing. The high-protection-level ultrasonic flowmeter housing adopts an independent glue potting box and a glue injection exhaust structure, thereby greatly improving its sealing protection level and product packaging efficiency.
