The 4-20mA analogue output is optional and is used for measuring the flow rate.
The output current varies linearly to the flow rate between 4mA and 20mA.
The 4mA value represents the null flow rate while the 20mA value is the maximum flow rate
(Q
4
) which varies according to the diameter of the meter.
The 4-20mA output of the E-Bulk is a passive circuit and must be powered by an external
device not supplied to the customer.
Parameter Value U.M.
