Target Flow Meters

 

The Niagara NFP Series ForceMeter™ is an insertion type flow meter that can measure water or steam. It utilizes a hermetically sealed strain-gage bridge circuit to convert flow force to a two-wire 4-20 mA output signal that is proportional to flow rate. All wetted parts are 316L stainless steel and the meter mounts to 4" and larger pipes using a 2" or 4" ANSI 150# or 300# raised face flange. The NFP Series comes pre-calibrated and configured based on the application parameters provided at the time of order; the meter only needs to be zeroed to adjust for installation orientation. Many different models and configuration options are available, such as retractable insertion types, inline models, and hazardous approval.
