Notes:
1 For viscosities of 3 CPS or less. Derate per pressure drop curves for higher viscosites.
2 Limited by meter seal material, transmitter model, orientation and ambient temp. See manual. Consult factory.
3 Some materials may have different filter requirements. Consult factory
4 Typical. See flow meter/transmitter calibration sheet for actual K-factor and accuracy data.
