MRR-841 Series

Features

Ultra Compact Footprint- Ideally suited to use in semiconductor tools Provides both local and remote flowrate information - 7 digit display and 0 - 5 vdc output signal.

Includes two user-settable alarms-provides "flow switch" functionality Simple to setup, scale and install Incorporates liquid -tight input /output signal conectors - ideal for wet process tools.

■

The MRR-841 is an ultra-compact Digital Display / digital-to-analog converter specifically designed to be used with Malema's MW Series paddlewheel flowmeters. The MRR-841 incorporates both a user-scalable 7-digit LED display that displays fluid flowrate and two user programmable alarm (Hi/Lo) points; Alarm status is shown both on the Displays front panel and open collector outputs are included for use in remote monitoring.

Operations

The MRR-841 accepts a pulse signal generated from a flowmeter such as Malema's MW Series paddlewheel meters and by continuously measuring the incoming pulse frequency and applying the appropriate scaling factor, displays the rate of fluid flow (GPM, liters per minute, etc.) on the front panel. The MRR Series also converts the flowmeter pulses to an analog signal (0-5 vdc) for use in remote monitoring applications.
