2. DPW FLOW METERS TECHNICAL DATA

2.1 - Principles of Operation

PW liquid flow meters consist of a meter body that is installed in-line in a conduit

D

ystem. Inside, between the inlet and the outlet connections is a rotary wheel with

s

ermanent magnets embedded at 180 degrees in paddles.

p

Fluid flowing through the meter causes the paddle to spin. A magnetic sensor picks
up the frequency of pulses, and the readings are proportional to the liquid flow
taking place. The number of pulses per unit time interval and a K-factor (pulses/unit
of flow) facilitate determining the volumetric rate of flow through the meter.

Additionally, the DPW Flow Meter incorporates a Microcontroller driven circuitry
and non-volatile memory that stores all hardware specific variables. The flow rate
can be displayed in 29 different volumetric or mass flow engineering units. Flow
meter parameters and functions can be programmed remotely via the RS-232/RS­485 interface or locally via optional LCD/KeyPad. DPW flow meters support various
functions including: two programmable flow totalizers, low, high or range flow and
temperature alarms, 2 programmable optically isolated outputs, 0 to 5 Vdc / 4 to 20
mA analog outputs (jumper selectable) for each process (flow and temperature)
variable, self diagnostic alarm. Optional local 2x16 LCD readout with adjustable
back light provides flow rate, temperature, total volume reading in currently
selected engineering units, diagnostic events indication and feature a password
protected access to the process parameters to ensure against tampering or
resetting.

2.2 - Electrical Connections

DPW flow meter is supplied with “M16” cylindrical 12 pin connector. Pin diagram is

ARNING

W

o avoid risk of serious injury or death, make sure power is OFF when connecting

T

r disconnecting any cables in the system.

o

Do not apply power voltage above 2 Vdc. Doing so will cause

PW damage or faulty operation.

D

The (+) and (-) power inputs are each protected by a 300 mA M (medium time-lag)
resettable fuse. If a shorting condition or polarity reversal occurs, the fuse will cut
power to the flow transducer circuit. Disconnect the power to the unit, remove the
faulty condition, and reconnect the power. The fuse will reset once the faulty
condition has been removed.

Use of the DPW flow meter in a manner other than that specified in this manual or
in writing from Dwyer

®

, may impair the protection provided by the equipment.

2.2.2 Analog Output Signals Connections

CAUTION

When connecting the load to the output terminals, do not

exceed the rated values shown in the specifications. Failure to
do so might cause damage to this device. Be sure to check if the wiring and the
polarity of the power supply is correct before turning the power ON. Wiring error
may cause damage or faulty operation.

DPW series Flow Meters are equipped with either calibrated 0 to 5 or calibrated 4
to 20 mA output signals (jumper selectable). This linear output signal represents
0 to 100% of the flow meter’s full scale range.

WARNING

The 4 to 20 mA current loop output is self-powered (sourcing

type, non-isolated). Do NOT connect an external voltage source
to the output signals.

WARNING

Observe jumper configuration before connecting 4 to 20 mA

current loop load. Failure to make proper jumper configuration
(see Figure 5-1) may cause damage for output circuitry. Do NOT connect an
external voltage source to the output signals.
