I’m looking for flow meter recommendations for an agricultural chemical injection system. Current setup is a hydra cell metering pump, vfd, controller and surefire electro magnetic flow meter. It’s all mounted on a trailer with a 550 gallon tank. Line size is 3/4”. Typical flow ranges between 5 and 100 gallons per hour. My issue with the electro magnetic flow meter is that there is a wide variation in the batches that we pump on a daily basis, so the system needs recalibration for nearly every batch. I’ve even pumped a few batches with very low conductivity and the flow meter really struggles. Does anybody have a recommendation for a specific flow meter that would require very little recalibration for a wide range in batches, as well as being a robust and compact unit. The system is mobile and is subject to the wear and tear of bouncing down dirt roads. Thanks in advance!
