Abstract: the liquid turbine flow meter
scale check line reasonable method to introduce information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
1, liquid filter capacitance in the detection power turbine flowmeter
, should be the electrolytic capacitor is negative short circuit, and cannot be used when a short circuit pens and line instead of a wire to discharge of capacitor, because it is easy to burn out the core.
You can take a lamp.
More flow meter manufacturers choose model price quote you are welcome to inquire, is liquid turbine flow meter scale to check the wiring and reasonable method introduction for details.
1, liquid filter capacitance in the detection power turbine flowmeter, should be the electrolytic capacitor is negative short circuit, and cannot be used when a short circuit pens and line instead of a wire to discharge of capacitor, because it is easy to burn out the core.
Can take a lamp holder leads 220 v, 60 ~ 100 w lamp, connect to the ends of the capacitor, the discharge lamp will flash moment.
2, when using a multimeter ohm block, bear in mind that cannot be charged.
Using logical pen, oscilloscope signal detection, to pay attention to not make the probe contact two measuring pins at the same time, because the essence of this kind of circumstance is in electric power form a short circuit.
Inspection instrument faults in damp environment, use multimeter for printing lines point whether tested according to the flow is necessary, because this kind of circumstance is the main failure of copper foil etching.
3, liquid test circuit inside the turbine meter repair the instrument, if the contact and the circuit boards of installing component, the coating insulating varnish, all point measurement parameters available welding on the multimeter pens and ordinary sewing needle, to puncture the lacquer layer directly measure each point, instead of a large area of stripping paint layer.
Can't charged plug all kinds of control panel and plug.
In charging case, the plug panel will produce strong induction electromotive force, then instantly counterattack voltage is very high, the corresponding control panel and the plug is easy to damage.
4, maintenance can not blindly on touch, lest expanding fault, the repair the bad.
Removing, adjust instrument, shall be recorded the original position, in order to recover.
Liquid turbine flow meter repair precision instruments and meters, small parts if they will play fly, should first judge may alight, do not look for east, west look, can take the magnet scanning and the line of sight scanning method.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
