cFMus Nonincendive for use in
hazardous (classified) locations:
Class I, II, III, Division 2, Groups
Detector and converter combination:
LF650/LF620: Combined type for standard specification.
LF650/LF622: Separate type for standard specification.
LF654/LF620F: Combined type with Ex approval of Class I, II, III, Division 2 (cFMus).
LF654/LF622F: Separate type with Ex approval of Class I, II, III, Division 2 (cFMus).
Mount-Anywhere Technology:
With TOSHIBA’s unique magnetic field distribution technology the meter is highly immune to upstream flow disturbances.
A minimum of 1D (one diameter) length of upstream straight pipe from the flange is required to maintain the specification performance.
Note: The test results were obtained and demonstrated at TOSHIBA's flow calibration facility, Fuchu Japan.
Drinking water approvals:
PU and HR liner: NSF certified
