Does the forum sell level gauges such as E+H or those from other brands?

The company used to have this model; I’ve forgotten its exact structure. It seems it was something like the diagram I drew – it was used for measuring the liquid level in vacuum tanks. I’m not sure if my diagram is accurate. Could anyone tell me the exact model name? Or information on manufacturers that use similar designs would also be helpful
I think E+H only has flowmeters; I know there is a level gauge called HE, which is of the differential pressure type
There are still many E+H instruments. This one is of the single-flange type, with a connecting tube to balance the pressure; I just forgot the model number

It seems that a conductive tube can be added in front of this flange to balance the negative pressure
There are quite a few manufacturers that produce these; Yokogawa also makes them. There are many domestic manufacturers as well, producing single-flange differential pressure transmitters
E+H single-flange, as well as E+H servo level gauges
