These rugged in-line flowmeters are ideal solutions for applications using water, water/glycol coolant and other low-viscosity fluids. They have no moving parts and operate with NPT ports ranging from ¼ ins. to 2 ins. and can handle flows from 4 gpm to 200 gpm with occasional over-ranging up to 125% of capacity without damaging the meter. They feature 4-20 mA flow rate transmitters and can withstand working pressures from 10 psig to 300 psig.
