Timer Based Feeders

Pulsation Series T7 was designed to feed chemical products on a timed schedule. Typical applications include the feed of biocides in open-air cooling towers. The feed cycle is initiated and controlled by the programmable timer. The Series T7 provides a unique, compact package to create a simple and cost effective metering system for timed applications. A 7-day programmable timer controls the Series T7. The timer is programmable in 1-minute increments with up to 8 on/off cycles per day. Each timed event can be set to run any day of the week on a 7-day cycle. Other control features include a standby mode, continuous ‘ON’ mode, and the ability to adjust the stroke length from 0 to 100%.

Four distinct models are available, having pressure capabilities to 100 PSI (7.0 bar) @ 12 GPD (1.9 lph), and flow capabilities to 48 GPD (7.6 lph) @ 50 PSI (3.3 bar), with a turndown ratio of 10:1. Metering performance is reproducible to within &plmn; 3% of maximum capacity.
