Accurate measurement in air conditioning, dust collection, ventilation, energy consumption, potable/non-potable water, acid, oil, gas, and other applications can be accomplished by CalFlo calorimetric flow meters. These meters are easy to install and their high-quality construction will withstand industrial use.

The CalFlo™ CFVF2 Thermal Mass Liquid Flow Meter is a great choice for a wide range of liquid applications. The
CFVF2 provides high accuracy measurement of flow, including very low flow rates, using a solid-state design with NO
moving parts. The CFVF2 features an adjustable measuring range easily adjusts to variable insertion depths, and fit
pipes up to 24” in diameter. Typical applications include potable water, non-potable water, deionized water, sulfuric
acid, light oil, and diluted corrosive liquids.
