Direct Replacement Hydrastep Probes

Hydrastep is just a brand name, but it is often used to describe the hype of equipment used for electronic drum level indicators. The brand "Hydrastep" has changed hands many times over the years, and now it is owned by Delta Mobrey, a company without the knowledge or experience of these products. Drumline probes are much cheaper and more readily available. Drumline will continue to stock the highest quality direct replacement probes for the systems Delta Mobrey has made obsolete.

Hydrastep was developed in conjunction with the CEGB, the UK’s Central Electricity Generating Board in the mid-1960s. Referred to as the Hydrastep 7, the system comprised of a vertical water column mounted to the steam drum with a series of probes spaced along the column. These were linked to the electronics mounted within a large floor standing cabinet with a visual display. This replaced an even earlier version, though there is little known detail of this. Performance trials of the Hydrastep 7 were carried out in the period 1968 to 1972 in several UK power stations. Manufacturing commenced in 1972 with the first installations in 1973. Marketing of Hydrastep into the United States began in 1983 with the first installation in 1984.
