These clamp-on flow meters provide a simple, accurate way to monitor water flow rates in aquaculture systems, hatchery plumbing, and other PVC pipe installations. Six models cover pipe sizes from 1" to 4", with flow ranges starting at 5 GPM on the 1" model and reaching 600 GPM on the 4" model. Each meter reads in both gallons per minute and liters per minute on a dual-scale display.
Installation requires only an 11/16" hole drilled into a horizontal section of pipe. The meter mounts vertically on a horizontal pipe and secures with two stainless steel clamps included with each unit. For accurate readings, install the meter at least 10 pipe diameters downstream from the nearest fitting or restriction on the inlet side, and 5 pipe diameters on the outlet side. Maximum operating temperature is 120°F and the maximum pressure is 120 psi.
All six flow meter models are easily disassembled for cleaning, and a single replacement float fits every size in the lineup. Whether you are monitoring flow in a recirculating aquaculture system, verifying pump output, or checking flow rates through a filtration loop, these meters deliver reliable readings without complex plumbing modifications or specialized tools.
