Series 4300 Totalizer

Featuring 5 digits of rate and 8 digits of total, the INVALCO 4300 is a battery- or loop-powered indicator capable of accepting magnetic pickup, DC pulse or switch closure inputs from pulse producing flowmeters. The unit can be ordered with an optional 4-20mA output (Models 4300-3I and 4300-3O). The 4300 uses the 4-20mA loop to provide power when this output is used.
