摘要： A valve arrangement for a guided wave radar level gauge including a valve housing holding a movable valve element having a through-opening, the movable valve element being configured to be movable between an open position and a closed position. A probe section arranged in the through-opening of the movable valve element. Upper and lower probe sections are located on respective sides of the movable valve element. A spring-loaded connection assembly is configured to form an electrical connection between the upper and the lower probe section via the probe section in the movable valve element when the movable valve element is in an open position.

摘要： The present invention relates to a method of verifying a measurement accuracy of a level gauge system. The method comprises determining a first measurement value indicative of a time-of-flight of a first electromagnetic reflection signal to a reference reflector and back; determining a measurement unit verification measurement value based on a response signal from a verification arrangement; determining a second measurement value indicative of a time-of-flight of a second electromagnetic reflection signal to the reference reflector and back; and determining a verification result based on the first measurement value, the second measurement value and the measurement unit verification measurement value. Through embodiments of the present invention, it will be verified that the measurement unit is functioning correctly and that level gauge system works as it should also after being reconnected to the propagation device.
