Fluid conductivity:
3µS/cm minimum
Fluid temperature:
-4 to 248 °F
(
-
20 to +120 °C): PFA lining
-4 to 104 °F
(
-
20 to +40 °C): Polyurethane lining
* Consult Toshiba before using the meter at the
high temperature, because the product lifetime may
be shortened.
Ambient temperature:
-40 to 140 °F
(
-
40 to +60 °C):
Separate type for PFA lined flowmeter
-4 to 140 °F (
-
20 to +60 °C):
Combined type for PFA lined flowmeter
-4 to 140 °F (-20 to +60 °C):
PU lined flowmeters
Structure:
Standard — IP 67 and NEMA 4X
Option — IP68 and NEMA 6P Submersible type
allows for accidental submergence up to 15m for 48
hours. PFA and Polyurethane lined detector tubes
are NEMA 6P/IP68 compliant when a TOSHIBA
approved Potting kit is properly Field or Factory
installed.
NOTE: PFA lining detector shall become valid the
IP68/NEMA 6X function after being connected the
pipe line. It needs to avoid being put under the rain
or water by itself before connecting.
Power consumption:
Without communication function
15W (22VA) or less
When standard is used;
(10W(14VA) at 100Vac and Excitation current:
0.2A)
With communication function
17W (24VA) or less
Approved hazardous location certifications:
Model: LF654/LF620F and LF654/LF622F
cFMus Nonincendive for use in hazardous
(classified) locations:
Class I, II, III, Division 2, Groups A-G
Detector and converter combination:
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 and 0D (zero
diameter) length of downstream straight pipe from
the flange are 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:
NSF/ANSI standard 61 (see Table 4)
 Model LF654 Detector
Mounting style: Flange connection type
Fluid pressure:

1.0 bar (
-
0.1 MPa) to the nominal
pressure of the connection flange (see Figure 2)
