NANO-N units are designed to display a mA input and transmit a mA and/or pulse output. It also can provide an automated control of chemical feeds and other external devices via two control relay outputs.

The pulse output can pace a metering pump or convert a mA flow rate into contact style water meter pulses (like used in a MegaTron). Follow the steps below to program the Pulse Out based on the mA range of the flow device using an example of 500 gpm as the max 20mA signal:

1. In the Configure menu set the Pulse output to ON
2. In the Configure menu define what the flow rate from the flow device is for: a. 4mA as 000.0 (this is the flow rate of the device with no flow) b. 20mA as 0500.0 (this is the flow rate of the device at maximum)
3. In the Pulse Output menu define:
a. LoRate as 000.0 (this is the gpm flow rate at 4mA)
b. HiRate as 0500.0 (this is the gpm flow rate at 20mA)
c. HiMax as 0100 (this is the number of pulses out per minute it will produce at a 20mA)
4. Go to the water meter input menu of the controller you are sending the pulse output to and define the input
as 5 gallons per contact.
