The weight of the utility model beat ruler correction system device can be realized liquid level/object plane height Mechanical measurement (
Weight is transferred automatically and measuring system detects that weight reaches the fast reaction later of liquid level/object plane and completes decentralization cable length and surveys
Amount), and then can be used for correcting radar measured data, it is ensured that beat the accuracy of ruler.Simultaneously also using certainly after weight return
Checking device is reaffirmed.
Specifically, when measurement, start to transfer weight, when weight is transferred to liquid level/object plane, weight reach liquid level to be measured or
The responding device (tuning fork liquidometer) of object plane can detect liquid level/object plane feedback signal, and control system such as PLC system is according to sound
Fork liquidometer signal judges whether to reach liquid level/object plane.If judging, weight reaches material liquid surface/object plane in tank, and weight is at once
Stop decentralization.Meanwhile length is represented according to the number and every signal of the photoelectric sensor of photoelectric code disk reception signal, under can get
The length of cable laying rope.Further, weight can be also retracted after the measurement has been completed using self-checking system specifically as camera confirms
Whether weight reaches liquid level/object plane.
Good effect possessed by the utility model is:
1. providing measuring device for grain and oil silo and oil tank:
2. reaffirming for ruler measuring system is beaten as radar, for correcting the data of radar, it is ensured that beat the accuracy of ruler.
3. situation is completed a business transaction in the clear plant capacity of energy and trade.
The utility model is related to below and is described in detail.
Detailed description of the invention:
Fig. 1 is that the weight of the utility model plays the schematic diagram of ruler correction system.
