9. Specifications

The flowmeter specifications and the type specification code used when ordering the flowmeter
are described in this chapter.
9.1Specifications
Meter size: 1/2, 1, 1 1/4, 1 1/2, 2, 2 1/2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18 inch
(15, 25, 32, 40, 50, 65, 80, 100, 125, 150, 200, 250, 300, 350, 400, 450 mm)
Measurement range in terms of flow velocity:
0 – 0.98 ft/s to 0 – 39.4 ft/s ( 0 – 0.3 m/s to 0 – 12 m/s).
0 – 0.3 ft/s to 0 – 1.0 ft/s (0–0.1 m/s to 0–0.3 m/s) range is available optionally.
System accuracy:
Accuracy: ±0.2 % of Rate*
* This pulse output error result is established under standard operating conditions at Toshiba admitted flow calibration
facility. (NIST Traceable).
* Individual meter measurement error may vary up to ±0.5% of Rate at 1.64 ft/s (0.5m/s) or more and ±0.3% of rate
±0.039 inch/s (1mm/s) at 1.64 ft/s (0.5m/s)or less.
* Current output: plus ± 8µA (0.05% of span.)
* Refer to individual calibration data for each individual meter's measurement error.
Fluid conductivity:
Fluid temperature:
Ambient temperature: - 40 to 140 °F ( - 40 to +60 °C):PFA lined flowmeter less than 8"
Fluid pressure: –15 psi or –1.0 bar (–0.1 MPa) to the nominal pressure of the connection flange.
Connection flange standard: See Table 9.3 Type Specification Code.
