Analog Input
As an alternative to the pulse inputs, the Series 3050 BTU flow monitor can accept an Analog input . The input is non-isolated,
but can accept 0…1V DC, 0…5V DC, 0…10V DC, 0…20 mA and 4…20 mA with both factory-defined and custom units
of measure .
Low impedance 100 Ω input for current inputs optimizes performance and flexibility or loop power supplies . Both the
low-end and high-end scaling are independent and can be field-configured .
