The IR-Opflow range of flow meters will meet the requirements for most metering applications effectively, accurately and economically. Available in 1% and 3% accuracy versions, these meters can be fitted with hose barb, NPR, BPS or metric threads.
All sizes are inherently linear, so they never require any signal conditioning gymnastics to smooth out a flow curve. Each meter size uses a specific K-factor. Plug that into a display or supervisory system and forget it. From zero to full flow, these meters are accurate and never disappoint.
