DESCOIPTION
Designed to meet the ever-changing requirements of flow metering, the Model 4050 flow computer can be tailored to
virtually any flow application It can accept up to three meters, correct for temperature changes and produce a usable output
in any flow unit The Model 4050 flow computer can work with manifold systems and switch relays with adjustable trigger
points This output can be used to change valve states and select active flow meters
Each Model 4050 flow computer is programmed to your individual requirements, and software is written for each unit when
required Each Model 4050 flow computer comes standard with a frequency input card, an analog input card, a relay card and
a communication card Other cards are optional as shown below Please contact your distributor for additional options

Data Entry
All calibration data is entered using the handheld infrared remote control after a successful passcode entry
To prevent incorrect data entry, when two Model 4050 flow computers are positioned in close proximity, the
reception of the computer that is not being addressed can be inhibited by a sequence of keystrokes on the
front panel of that computer (See
"Disabling and Enabling the Remote Control" on page 13
