It is mounted in the same cavity with main control board, when dismantling main control board or battery, is easy to generate metering circuit dry
It disturbs, keeps measurement data unstable, while on-site maintenance difficulty is also relatively high.
（2）The water flow pressure in runner cannot be measured in real time, be had a single function, if to measure water flow pressure,
It needs using other pressure checking device, it is troublesome in poeration.
Summary of the invention
The purpose of the utility model is to provide a kind of ultrasonic water meters, to realize that hydraulic pressure detects, while reducing and believing measurement
Number interference, reduce on-site maintenance difficulty.
Ultrasonic water meter described in the utility model, including electronic watch head, measurement pipeline section, ultrasonic transducer and measurement electricity
Road plate, the ultrasonic transducer is mounted on the two sides of measurement pipeline section, and its probe protrudes into the runner of measurement pipeline section, lead
Fairlead and measuring circuit plate on measurement pipeline section weld；The top of the measurement pipeline section has electronic device installation cavity,
The electronic watch head be mounted on the upper end of measurement pipeline section and with electronic device installation cavity face, the measuring circuit plate is mounted on electricity
In sub- device installation cavity, the center of measuring circuit plate offers avoid holes, a hydraulic pressure sensor（For measuring the water flow in runner
Pressure）Across the avoid holes and be mounted on the center of electronic device installation cavity, measuring circuit plate, hydraulic pressure sensor by lead with
Main control board electrical connection in electronic watch head；The measuring circuit plate, hydraulic pressure sensor and be located at electronic device installation cavity in
Lead fixed by glue package.
The side of the electronic watch head is equipped with communication module, and communication module is electrically connected with the aviation socket in electronic watch head
