HT5 series metal tube flowmeter
detected and the corresponding instructions.
Output current deviation detection step instructions:
Confirm pointer correctly (if there is no standard site traffic detection method is the
only one float falls below the pointer points to accurately indicate the RP). And then to
push the float detected indicating correspondence between the outputs.
Check the pointer shaft retaining ring is loose, testing and adjustment methods:
Phenomenon: Zero or 4mA output current does not indicate the presence of severe action
inflexibility
Detection method: Gently pull the pointer up tube to see whether it has caused the
relocation of large gap between the bearing and the phenomenon. This problem is usually
transportation vibration or Flow rate long-term instability, this problem is likely to cause
a pointer attached to dial or touch the magnet coupling housing problems caused by
instructing the operation is not flexible, and the output current is zero deviation.
Pointer bearing retaining ring loose approach:
Remove the dial (be careful not to touch the rigid pointer), unplug the power from the left
side with a small screwdriver to unscrew the screw fixing the converter, the converter can
be removed. (Note must be light breaking guide rails prevent damage), then remove the
Phillips screws on the rail, you can remove the entire axis system will remove the right
side of the frame.
The coupling system pointer on a clean flat position (such as iron, etc.), and then use
the hex wrench to loosen the stop ring on the top wire, so that the stop ring and bearing
bearing snapping up (but pay attention to ensure that there is a gap that feeling a little
displacement exists gently pull pointer, such action is not likely to cause too tight
flexible.
Such as tight coupling portion can be picked up, knocking down light sensing component
parts to make it flexible. Replace as is.
Screw rail to be tightened, check the status of whether the rotation axis have the
phenomenon of the card.
Converter testing and adjustment:
Power Detection: Connect the converter measured after the supply voltage, if the voltage
