Vacuum negative pressure condition be in material container C, atmospheric pressure state is in due to measuring container 16, with tested material container C-shaped into one
Level pressure is poor, and vacuum will measure material in container 16 and be sucked back by discharge pneumatic operated valve 21 and drainage conduit 20 in tested material container C, survey
Sample is measured to return.If be in atmospheric pressure state in tested material container C, or with measurement container 16 between pressure differential it is too small, measure
Sample can not be quickly recycled in tested material container C, and controller A is by instruction unpack intake valve 2 and closes exhaust-valve 4, leads to
Cross compressed air in air inlet pipe 1 to enter, the increase measurement chamber pressure of container 16, material samples are delivered in tested material container C；
Sample reclaims；Discharge pneumatic operated valve 21 is then shut off, opens exhaust-valve 4, by the measurement inner high voltage air of container 16 discharge.Now complete
One-shot measurement.Said procedure is circulated, so as to realize continuous online batch (-type) measurement；
（5）When measurement reaches setting measurement number or run time, by program automatically into the measurement internal washing stage of container 16,
Operating procedure：
Cleaning, opens water intaking valve 7 and exhaust-valve 4, and water enters measurement container 16 by water pipe 22 from water pipe 6, rinses and soak floating
Body 17 and the measurement inwall of container 16；When water level rising touches 14 electrode of liquid level sensor in measurement container 16, controller A instructions
Water intaking valve 7 is closed.Certain time is waited, will measure salvage stores on the inwall of container 16 and floating body 17 by water cleans；Controller A
Instruction discharge pneumatic operated valve 21 is opened, will using vacuum in tested material container C if being negative pressure state in tested material container C
Water in measurement container 16 is sucked back in tested material container C；If in tested material container C it is atmospheric pressure state, or vacuum pressure
Difference is too small, and the water measured in container 16 can not flow automatically or slowly flow in tested material container C, controller A instruction intake valves 2
Open and exhaust-valve 4 is closed, measurement container 16 is entered by compressed air, the hydraulic pressure measured in container 16 is entered into tested material holds
In device C, discharge pneumatic operated valve 21 is then shut off, opens exhaust-valve 4, by the measurement inner high voltage air of container 16 discharge.It is repeatedly above-mentioned clear
Washing procedure 2-3 times, cleaning operation step is completed, while the present apparatus completes self-calibrating function, waits to enter Brix Measurement next time.
