Description
Technical field
This utility model relates to a kind of assay device, refers more particularly to the pipeline of a kind of intelligence piston volume tube assay device
Liquid closed circulating device.
Background technology
The intelligence piston volume tube assay device metering to flow, the metering to temperature and to the calculation of heat energy all
The accuracy of thermal metering can be produced considerable influence；Accuracy in order to ensure flow meter thermal metering, it usually needs make stream
Scale has and meets necessarily required flow measurement accuracy, temperature measurement accuracy and heat energy accuracy in computation etc.；Cause
This, flow meter is before dispatching from the factory or the stage such as maintenance would generally accept flow verification, temperature calibrating and calculation calibrating.
At present, calorimeter is carried out the implementation of flow verification usually: arrange and include pump, vacuum tank, standard
Table, calorimeter to be checked and the flow verification system in water tank/pond, first, hot water is extracted out from water tank/pond by pump,
Hot water flows back into water tank/pond after flowing through pump, vacuum tank, standard scale and calorimeter to be checked successively.Testing person is permissible
According to the standard scale metering adaptive adjustment calorimeter to be checked to flow, so that calorimeter to be checked is most to the metric results of flow
Possible is identical to the metric results of flow with standard scale, so that the flow measurement accuracy of calorimeter to be checked meets certain
Requirement.
In existing flow verification system, water tank/pond is typically open, and fluid leakage warms up with actual
Difference between logical operating mode is the biggest, and the calorimeter through flow verification system calibrating is being applied to actual HVAC work
Time in condition, often there is bigger error in its flow measurement result, thus the energy loss of existing flow verification system with
And flow verification accuracy all awaits further improving.
