General Information

PT32 Single Pulse Timer

PT33 Dual Pulse Timer

Instructions

PT32 and PT33 pulse timers are designed for use with

SeaMetrics (or similar) meters and flow sensors which

produce a pulse signal. They can control metering

pumps or valves in a variety of cooling tower, boiler and

other water treatment applications. These units include

accumulators, which count pulses from the meter. When

a preset number has been reached, output power turns

on for a set time and then the cycle repeats.

For applications requiring dual timers (typically one for

feed and one for bleed), the PT33 has two timers and

accumulators in one enclosure. Input is from one meter,

but the accumulators and timers are set independently

of each other. A sequential feature locks one timer out

while the other is operating, to prevent bleed and feed

from occurring simultaneously.

A 12 VDC low-current meter loop is a standard feature.

This can be used with brass pulse meters, as well as

most of the SeaMetrics line of insertion, turbine, and

low-flow meters. Both dry-contact reed switch and solid-

state Hall-effect sensor signals are accepted.
