Problems solved by technology

Since the tester needs to record the number of times the listening and counting device rings while watching the stopwatch, when the calculation is disturbed by external factors, errors in the number of times are prone to occur, resulting in errors or errors in the measurement data
Flow monitoring accuracy cannot be guaranteed

Abstract

The invention discloses a counting device for the number of revolutions measured by a hydrological survey flow velocity meter, which is a device for measuring the flow velocity of a river channel by adopting a flow velocity meter method, and belongs to the technical field of flood flow monitoring tools. According to the automatic listening and counting device of the current meter, electronic information and electronic counting principles are applied, when a rotor of the current meter makes contact with an electric pulse signal converted by a mechanism, a sound module starts to make a sound, a testee presses a start key, a counting module and a timing module start to work, and when the time is about 120 seconds, and when the last sound is heard, the recording key is pressed down, the timing module and the counting module are stored and displayed on the display module, and the time displayed on the display module and the number of times of current signal connection of the current meter can be manually recorded. After a reset key is pressed down, the time and times of the next point are measured and stored, the operation is repeated until flow measurement is finished, recorded information is transmitted to a computer through Bluetooth, and the flow is calculated according to a calculation formula of the flow meter.

Description

technical field [0001] The invention relates to an automatic listening and counting device for a flow meter for hydrological measurement, especially capable of automatically recording the revolution number and time of the flow meter. The utility model belongs to the technical field of hydrological testing tools. Background technique [0002] At present, in the test method in the field of hydrological testing, generally one person holds the sounding rod, and the top of the sounding rod is connected to the current meter, and the other person holds the measuring device for measuring the number of revolutions of the current meter and listening to the sound counting device. When the current meter rotates to a certain number of revolutions, The listening and counting device sounds once, and the tester needs to press the stopwatch when the listening and counting device sounds, and listen to the number of times the listening and counting device sounds within a fixed time. When the t...
