Printed in this six-page, full-color brochure is information regarding the company’s microprocessor-based digital level transmitter/controller. The L3300 functions as an accurate level transmitter, while at the same time serves as a flexible multiple point/zone level controller. The brochure explains that the L3300’s 4-20 mA signal is always provided for continuous level measurements. Simultaneously, the L3300 can be set up to function as a multiple point level controller in one of five operating modes: four independent setpoints, one zone and three independent setpoints, two zones and two independent setpoints, lead-lag pump control for pump up, drain down with two independent setpoints; and lead-lag pump control for pump down, fill up with two independent setpoints. — Princo Instruments, Inc.
