The FLD100 Series heavy-duty 
flow meters are fully enclosed in a 
brushed stainless steel case. Ideal 
for industrial applications with flow 
rates up to 116 GPM and 
250 SCFM. Used with industrial 
water and air service. Meters are 
graduated for direct reading of 
water and air. Flow meters come 
standard with FNPT end fittings 
for easy in-line installation or ANSI 
150 flanges (-FL)
