Model 330 Programmable Relay Control

OVERVIEW

The Model 330 is a compact, programmable relay control
transmitter capable of converting the signal from a Badger Meter
flow sensor into a flow switch.

With an onboard microcontroller and digital circuitry, the Model
330 is programmed using a Windows® based computer program.
This eliminates the need to set dip switches or potentiometers and
produces precise, accurate and drift free control of the relay outputs.
In addition to accepting the Badger Meter square wave signal, the
Model 330 can accept other pulse and sine wave inputs.

The compact cast epoxy body measures 1.75" (44 mm) x 2.75"
(70mm) x 1.5" (38mm) and can easily be mounted to panels, DIN
rails or enclosures. With multiple inputs, ease of use and a variety of
enclosures, the Model 330 is a powerful, competitively priced relay
control device.

APPLICATIONS

Combined with a flow sensor the Model 330 can be used in a variety
of "Flow Switch" applications.

• Flow/no flow indicator

• High flow/low flow alarm monitor

• Booster pump control

• Multiple pump staging

• Leak control

Alarm Status Using the Windows software, the actual

relays, one normally open and one normally
closed. Both relays act in unison to the
programmed parameters.

The Model 330 can be programmed as
a high flow alarm where the relays are
energized when the flow rate exceeds the
set point, and/or as a low flow alarm where
the reverse is true and the relays energize
when the flow rate falls below the set point.

The set point—the flow rate where the
relays are energized—is programmed
independently from the release point— the
flow rate where they are de-energized. This
adjustable deadband prevents relay chatter
and control cycling.

This feature provides a time delay between
crossing the set or release point and
energizing or de-energizing the relay. This
feature allows surges in the flow to dampen
out before the control circuit reacts.
