Problems with the liquid level gauge can occur in three ways: high, low or unstable indications.First of all, check whether the liquid level meter is leaking, pass an air source into the positive pressure chamber and block the negative pressure chamber to see if there is any air leakage. The high indication is generally due to a leak in the negative pressure chamber, which increases the differential pressure; the low indication is due to a leak in the positive pressure chamber, which decreases t...
