PT34 Single Pulse Timer

PT35 Dual Pulse Timer

Instructions

General Information

The PT34 and PT35 digital counter-timers are designed

to be used with SeaMetrics (or similar) meters and flow

sensors which produce a pulse signal. They are typically

used in water treatment and chemical dosing applica-

tions, most often in cooling towers and boilers. The first

function of these units is the accumulator, which counts

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

chemical feed and one water bleed) the PT35 has dual

accumulators and timers. Input is from a single meter or

flow sensor, but the accumulators and timers are set in-

dependently of each other. A sequential function can be

selected to lock one timer out while the other is operat-

ing. This prevents feed and bleed from occurring simul-

taneously.

A 12 VDC low-current meter loop is standard. This can

be used with dry contact meters, as well as contacting-

head meters with solid-state pickups (SeaMetrics ME

meters) or insertion flow sensors (SeaMetrics IP line).
