The INVALCO Model WCM 7300ME is the insertion-probe version of the WCM 7300M temperature-compensated water cut monitor. It measures water content in crude oil, condensate and other low-dielectric liquids from a maximum of 25% down to 1,000 ppm, with full product temperature compensation for a true water cut from 25 to 160 °F. On large-diameter flow lines an insertion probe is often more economical than an inline spool. The 7300ME is NACE adaptable.

How to read the model code
Example: WCM 7300ME - 260 - BFP = 2" probe, 600# RF, standard carbon steel, flanged, epoxy.
Probe body size: 2 = 2" OD; 3 = 3" OD
End connection (2 digits): 00 = screwed, grooved/Victaulic or 150# ANSI RF (all printed as 00); 30 = 300# RF; 60 = 600# RF (SCH 80); 90 = 900# RF; 05 = 150# RTJ; 35 = 300# RTJ; 65 = 600# RTJ (SCH 80); 95 = 900# RTJ (SCH 80); 115 = 1500# RTJ
Material / temperature: B = A53B carbon steel, -20 to 160 °F; H = carbon steel high temperature, -20 to 375 °F; S = 316 SS, -20 to 160 °F; T = 316 SS high temperature, -20 to 375 °F
Connection style: S = screwed MNPT; G = Victaulic grooved; F = flanged
Last position (labeled "Open"): P = epoxy
Consult the factory for the temperature compensation factor
Bulletin errors to note: the first sentence calls the unit "Model WCM 7300M"; the display is described both as a four-digit LCD and as a two-line 16-character LCD; the code "00" is printed for three different end connections; some flange rows say "(For 8 inch and 10 inch)" although the 7300ME probe is 2" or 3"; and the dimension note says the 3" probe face-to-end is 18.00" instead of 33.00" for the 2". Confirm these details with the factory.
