Signet Scientific Co. P57540 Pressure Transmitter

Georg Fischer Signet's P57540 is a flow meter (Accum-U-Flow) model identified by part number P57540. It is manufactured under the Signet Scientific Co. banner and is listed as discontinued by the manufacturer. The unit operates on 12 VDC and weighs 1.98 lb, reflecting a compact, low‑voltage flow‑measurement device designed for integration into process piping where Signet’s Accum-U-Flow technology is employed. In distributor catalogs, the P57540 is cataloged as a flow meter rather than a pressure transmitter, distinguishing it within Signet’s legacy instrumentation lineup. This legacy device is positioned for applications requiring an accumulator flow solution and is encountered in secondary markets due to its discontinued status.
