Liquid level meter routine inspection and fault resolution method, applicable to the magnetic flap level meter, two-color quartz tube level meter, glass tube level meter, etc.
1, first check the power supply is connected to, if found that the wrong approach should be in accordance with the operating manual to modify.
2, with three voltmeter measuring the voltage between +24v and o/p, voltage should be between 13v~36v, if the voltage is not normal should see the line or related equipment is abnormal.
3. The 2nd item should first confirm normal, again in 4~20ma Circuit string a MA electric meter, check the current is normal, if the current value is abnormal should replace new product or contact customer service personnel.
4. Check in with the voltage meter in and COM voltage, normal should be about 2.5V, if the voltage is too low should be removed exc wire to see if the voltage return to normal, the magnetic yellow module is not normal, if the electricity is still low means that signal converter damage. If you find that the above phenomenon should be in accordance with the actual situation change signal converter or contact customer service personnel.
Floating ball to the bottom, the flag plate does not return to the zero flag plate and the speed of the falling ball, should be installed throttle device to reduce the speed of the liquid surface.
Flag plate color will not flip, or color film confusion should be confirmed that the body tube around and inside no magnetic body exists, and after the clearance with a magnet sweep once, so that the color is consistent.
Color film 360 degrees flip Floating ball magnetic field is too strong, contact customer service personnel to replace floating ball.
Close switch does not move the electric meter check whether the switch is normal, the magnet close to the contact should be conduction and the resistance should be below 300mω, the magnet removed after the switch should be open and the resistance should reach 10mω above, if not up to the requirements should be replaced by the new close switch.
Floating ball continuous liquid level indicator signal Converter 2 lines not how to receive a meter please follow the manual to have the 24V end of the signal converter on the +24v end of the indicator. Signal Converter o/p end to the AI end of the indicator, if the power is still not normal operation should contact customer service personnel.
