Near Intersection of I-35 & I-90 Southern Mn. | Yes, and what you are referring to is a "Flow Meter". It is not a valve, it does not control the flow. It reports the flow passing through it to the system. Your system does have a control valve or system which the system controls in an attempt to apply the target rate you have entered.
The meter cal is the number the system uses to convert the pulses created by the flow meter into familiar units such as gallons in this case.
The number stamped on a Raven Flow meter is the number of pulses produced when 10 gallons of water passed through the flow meter at the factory. Raven has always used the 10 gallon method since their first controllers did not have a decimal point on their keyboard and this was a way to get finer resolution.
Ag Leader does have a decimal point and their system uses a meter cal based on the number of pulses produced when 1 gallon of water passed through the flow meter. This is why you need to divide the Raven meter cal by 10 when using it with an Ag Leader system.
This is true for spraying and NH3. Do not use the Raven NH3 number in the Ag Leader.
The reason you are getting the "rate not responding" message is that by using a meter cal 10 times too large, the system is not able to apply 10 times the target rate.

Raven flow valve divide by 10?
