HT5 series metal tube flowmeter
plate from the tank is withdrawn and then detecting the pointer is flexible. If you remove
the alarm board and flexible operation, the fan-shaped plate observe pointer to cut the
initiator is not a part of the tank wall stickers starting problems. You can adjust the
pointer to the segment-type plate making flexible movement. Other as above.
6.2 Measuring tube
Metal tube generally does not require maintenance, if the medium contains ferromagnetic
particles or sediment, float stuck phenomenon may occur (This phenomenon occurred in the
new plant start-up phase, because the pipe is not clean sweep, welding slag, etc. when
attracted to the lead float float stuck) at this time regardless of the size of the flow
in the pipeline, only a pointer to the converter parked on a fixed scale (visible LCD display
instantaneous flow rate constant), the occurrence of this phenomenon, only traffic remove
the meter from the pipe to clear the obstruction to resume normal operation.
Note: If the card float problems, do not force knocking the measuring tube with a hard
object, or easy to make variations of the measuring tube damage.
To shut down Flow rate meter before removing the pipe, (HT52, HT53, HT56 meter without
the meter from the pipeline removed, simply close the valve, remove the upper and lower
seal fittings can see below the measuring tube removed solution Figure) if used in corrosive
media, to take safety precautions to avoid injury residue of the measuring tube. Remove
and re-install the meter (seals removed) after removal from the top of the float collar
and remove ferromagnetic substances and sediment, rinse the measuring tube and float collar,
attention should be guaranteed to run freely float in the measuring tube.
If the meter indicates instability in the system during operation, the measurement system
components should be checked condition, there are basically four reasons for this phenomenon:
First, the pipeline Flow rate is unstable; the second is the meter outlet pressure is too
small (usually measured prone when a gaseous medium) is less than 5 times the pressure loss
of the meter, if possible, should try to open the meter inlet valve, close the outlet valve
appropriate; Third, the meter range selection is too large, the flow meter in the lower
measuring range is not easy to establish a stable working conditions, should return the
manufacturer piecemeal measurement range. Fourth, the fluid to be measured in the presence
