I searched and saw a sensor for calsense on brass unions on a old thread. I will try and post pics next week.
We did a 2" Data Industrial PVC flow sensor with a couple of unions. We put about 24" of SCH 80 PVC on either side of the sensor between the sensor and the union. Didn't seem to have any issues with it. Data Industrial calls for a minimum of 10 times the pipe diameter in length on the downstream side of the sensor and 5 times the pipe diameter in length on the up stream side of the sensor.
