Flow detection and automatic control experimental instrument

The utility model discloses a flow check and automatic control experimental meter, comprising a water supply device of automatic circulation whose inner portion is provided with a water pump connected with a pipeline system by a flexible pipe. The inner portion of the pipeline system is orderly connected with an electromagnetic flow meter, a worm wheel flow meter, a wentouli flow meter, a hole board flow meter, a water level system and a liner motor. The water outlet of the pipeline system conducts backwater to the water supply device of automatic circulation by the flexible pipe. The electromagnetic flow meter, the worm wheel flow meter, the wentouli flow meter, the hold board flow meter and the water level system are respectively connected by each own sensor, secondary meter, flow check controller and computer. The utility model belongs to the table type experimental device of intensity technology type. The flow check system and the automatic control system in the industry are adopted into the traditional experimental system of the engineering hydromechanics to be suitable for the requirements of the modern teaching. The system can conduct synchronous check to various flow meters in various flow with the functions of computer data collection, flow and water level mark, flow automatic control, etc.
