HAWK’s Variable Area Flow Meters
Three defining traits of HAWK’s Variable Area line of flow meters are easy installation, accuracy, and low maintenance. So durable and reliable, most last over 30 years. These meters are no ordinary volumetric flow meters. With an excellent tolerance to suspended solids, no need for straight runs of pipe, and over thirty years of tried and true use in harsh applications, these flow meters are ideal for a wide variety of applications.

The HawkVFlo HFVC PVC & CPVC flow meters are simple, accurate variable area meters and resistant to many acids, alkalis, salt solutions, and other corrosives. These meters have an excellent tolerance to suspended solids and measure flow to one percent accuracy. Unlike tapered tube rotameters, the HawkVFlo HFVC flow meters have an indicator disk in close proximity to the edge of the sight tube for visibility even in many dirty fluids. Alternatively, magnetic indication is available for accurate reading regardless of media. These meters can be supplied with the HFT2 2-Wire Transmitters for flow rate and total.

The HawkVFlo HFTV Metal Bodied Flow Meters with Clear Top are simple, accurate, meters for use in a wide range of industrial liquid and gas applications. These meters have an excellent tolerance to suspended solids and measure flow to one percent accuracy. Unlike tapered tube rotameters, HFTV flow meters have an indicator disk in close proximity to the edge of the sight tube for visibility even in many dirty fluids. These meters can be supplied with the HFT2 2-Wire Flow Transmitters for flow rate and total.

The HFT2 two-wire flow transmitter accurately calculates and outputs flow rate. Compatible with any HawkVFlo variable area flow meter, HFT2 combines HAWK's time-proven variable area technology with a high tech processor and solid state circuitry.

The HawkVFlo HFHM High Pressure Flow Meter is offered in liquid and gas configurations, this flow meter is a great choice for a diverse range of flow services. Liquid examples include hydraulic oil, grease, solvents and dirty fluids including mild slurries. Gas examples include compressed air and digester gas.

HawkVFlo HFAM All Metal Flow Meters are simple, accurate, meters for use in a wide range of industrial liquid and gas applications. These meters have an excellent tolerance to suspended solids and measure flow to one percent accuracy. With an all metal design, these meters are ideal for high pressures, high temperatures, steam, dirty fluids, and harsh service environments. HFAM All Metal Flow Meters use an internal magnet to carry an external indicator in a non-wetted enclosure. And they can be supplied with the HFT2 2-Wire Transmitters for flow rate and total. Additionally, these meters can be supplied with a high temperature indicator option for service up to 600°F.
