Fluid temperature:

-4 to 248 °F (-20 to +120 °C):

PFA lined flowmeter

-4 to 140 °F (-20 to +60 °C):

Polyurethane lined flowmeter

23 to 176 °F (- 5to +80 °C):

Hard Rubber lined flowmeter

Ambient temperature:

-40 to 140 °F (-40 to +60 °C):

PFA lined flowmeter

Structure:

Standard — IP 67 and NEMA 4X Watertight

Option — IP68 and NEMA 6P Submersible type

allows for accidental submergence up to 15m for
48 hours. This option is only available when

or HR liners are selected.

Power consumption:

Standard:10W(14VA)
at AC100V and Excitation current:0.2A

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:

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



pressure of the connection flange.

Note: Before shipping from the manufacturer, each detector

unit is tested by the following test condition.
Pressure… twice of the pressure index number
(ex. 300 psi in case of ASME B 16.5 class 150 flange)
