Come complete with operator’s manual and correlation sheets for water and air.
1. To order units without valves, add suffix “-NV” to model number, for additional cost.
2. To order units with high resolution valves, add suffix “-HRV” to model number, for additional cost.
†
For optional 10-point NIST certificate add suffix, “-NIST” to the model number, for additional cost and two weeks to the standard lead time.
Ordering Examples: FL-5651T-HRV, 150 mm glass tube, stainless steel-tantalum float flowmeter with high resolution valves.
