详细介绍

Dwyer PFT系列转轮流量传感器Non-Magnetic Sensing, Adjustable for 1-1/2 to 40" (38.1 to 1016 mm) Pipe, Pulse or 4 to 20 mA

The SERIES PFT Insertion Paddlewheel Flowmeters are used to monitor liquid flow rates in pipes from 1-1/2 to 40" and is available in brass or 316 SS body. The unit outputs a frequency proportional pulsed or 4 to 20 mA output. The pulse models are a square wave output signal with frequency proportional to the flow velocity and the 4 to 20 mA models have a linear output of the velocity with 4 mA equal to 0 ft/s and 20 mA equal to 25 ft/s.

Service:

Water-based fluids.

Range:

1.2 to 25 ft/s (0.37 to 7.62 m/s).

Wetted Materials:

Body and fitting: Brass or 316 SS; Fitting O-ring: FKM standard, silicone or Buna-N optional; Impeller: 316 SS; Shaft: tungsten carbide standard or 316 SS optional; Bearing: PTFE standard.

Linearity:

±1.0% of FS.

Repeatability:

±0.5% of FS.

Temperature Limits:

-40 to 212°F (-40 to 100°C).

Pressure Limits:

400 psig (27.6 bar) @ 100°F (37.8°C), 325 psig (22.4 bar) @ 212°F (100°C).

Process Connection:

1-1/2" NPT male standard, 2" NPT male optional.

Output:

> Pulse: NPN open collector with square wave output, rated 60 V @ 50 mA maximum.
Frequency: 3.2 to 200 Hz. Pulse Width: 2.5 msec ±25%.
4 to 20 mA: 4 mA is 0 ft/s, 20 mA is 25 ft/s.

Power Requirement:

10 to 35 VDC.

Power Consumption:

40 mA (max).

Electrical Connection:

22 AWG shielded UL type PTLC rated 105°C, 20' (6.1 m) long with cable gland. Can be extended up to 2000' (609 m) with similar cable. Optional UL listed burial rated cable.

Enclosure Rating:

NEMA 6P (IP67) *.Dwyer PFT系列转轮流量传感器

Housing Materials:

Brass or 316 SS.
