Drumline is a UK company that has been developing and manufacturing conductivity level probes for over 10 years. Our range of direct replacement level probes is for Electronic Dum Level Indicators and Electronic Level Switches made by Hydrastep, Delta Mobrey, Cesare Bonetti, Clark Reliance, Fossil, Levelstate Systems (Hi-tech Systems India), Yarway, Narvik, BHEL, Questtec Systems, and RAC Energy.

Drumline manufactures probes with the same, if not higher standards than OEMs', because we have OEM experience, including decades of designing and manufacturing probes for OEMs, including ones we sell direct replacement probes for now. Drumline maintains a large stock of most probe models, meaning we can fulfil virtually all orders quickly from stock. Drumline has a simple purchasing procedure, which reduces the time between order and completion. Boiler Drum Level Probes
