MODEL CODE

OUTLINE

Adding the radiator fins on the well-established W-2000 series, the

W-3000 mini-wheel flowmeter series makes it possible to measure

liquids as high as 150°C.

This model is suitable for assembling in the semiconductor chiller

devices for high temperature services.

FEATURES

❏ Compact and light weight design with a precision casting body

❏ Open collector pulse output available

❏ Continuous measurement of high temperature services up to

150°C with radiation fins

❏ Easy overhauling, cleaning and maintenance

❏ Complying with RoHS

STANDARD SPECIFICATION

● Measuring liquid

: Liquids including Fluorinert and

Galden

● Allowable viscosity

: 2 mPa • s or less for models W-3012

through W-3015

3 mPa • s or less for models W-3016

through W-3019

● Fluid pressure

: Max.1.0 MPa

● Fluid temperature

: Max.150°C

● Ambient temperature

: Max 50°C (Without dew condensa-

tion)

● Flow direction and posture : The pipe line on which flowmeter is

installed, is either in horizontal or

vertical. For the installation on

horizontal pipe, the wheel shaft

must be always in horizontal and

flow path (center line of pipe line)

must be situated in the upper side

of the wheel to fill the wheel cham-

ber fully with liquids.

● Construction

: Indoor use (equivalent to IP20)

● Output

: Open collector pulse (Unscaled

pulse)

● Duty

: H (Changing depending on flow

rate)

L (2 ms for reference value)

● Pulse frequency

: Approximately 75 to 95 Hz at the

maximum flow rate (Actual mea-

surement value indicated on tag

plate)

● Power supply

: 5 to 12 VDC, 12 mA

● Load rating

: Max. 12 VDC, 15 mA

● Accuracy

: ±5% F.S. for model W-3012

±3% F.S. for models W-3013

through W-3019

● Electric connection

: AWG 26 (12/0.12) x 3-core

UL 2941 4-core cable (Green: Non-

use)
