TS Series Liquid Flow Meters NTEP Approved Industrial Series NTEP Approved FPP flow meters provide high accuracy performance with only 2 moving parts. Low pressure loss, and lack of metal to metal contact anywhere in the flow meter, result in low wear factor and minimal maintenance requirements. Industrial Series FPP flow meters are available with either mechanical or electronic registers, and can be assembled to suit the most demanding operational requirements. Electronic assemblies are gland-less, and can have the display either mounted or remote. Repeatability of FPP Meters is commonly +/-0.05% under constant conditions. In systems with fluctuating flow rates, overall accuracy is usually better than +/-0.3% over a 10:1 turndown. Multi-point calibration for enhanced accuracy over full operating range is available in many of the electronic registers.
