Chilled & Hot Water and Water/Glycol Mixtures

The Hydro-Flow Models 2200 and 3100 insertion flow meters are recommended for supply, return, and bypass water systems larger than 3". These models withstand process temperatures as low as 32°F (0°C) and as high as 160°F.

Condensate and Hot Water

The Hydro-Flow™ Models 1200, 2200, and 3100 are recommended for measuring condensate. These models withstand process temperatures up to 160°F. As the Hydro-Flow vortex sensor contains no moving parts, excessive mechanical loads on the flow meter, caused by continuous start-stop flow (sudden acceleration and deceleration of flow) as condensate is pumped from a holding tank, do not affect the accuracy or mechanical reliability of the flow meter. Additionally, the Hydro-Flow flow meter with no moving parts will not be affected by possible iron, salt, or other deposits.

Potable and General Water

All Hydro-Flow series flow meters are recommended for domestic potable water and general water applications.

Turf and Landscape Irrigation & Agricultural Water

Hydro-Flow flow meters can be used with irrigation controllers manufactured by RainBird®, Weathermatic®, Rainmaster®, Motorola®, and TORO®. This, coupled with standard features, like the NEMA 4 rating and a turndown ratio of 15:1, make Hydro-Flow series flow meters ideal for control and measurement of water in turf, lanscape irrigation, and agricultural applications.

Ultrapure Water, Deionized Water, Acids & Solvents

The Model 2300 is manufactured from PVDF for flow measurement of ultra-pure water, deionized water, acids, solvents, and other corrosive fluids, making it an ideal solution for use in semi-conductor and chemical wet processes. The Model 2300 design has no internal crevices, or "dead space", eliminating the risk of bacterial growth and contamination. Unlike traditional paddlewheel and impeller type flow meters, which can wear over time or shed particles into the system, the Hydro-Flow's series no moving parts technology eliminates the possibility of fluid and process contamination.



The Model 2300 is designed to retrofit into most +GF+ Signet® fittings without modification of the existing piping system.

For 1" to 3" Line Sizes

• Model 1100 with either PVC Schedule 80 tee fitting or 150# flanged body for installations with PVC piping
• Model 1200 with brass tee fitting with threaded connections for steel and other metal piping
• Model 2200 with brass tee fitting with threaded connections for steel and other metal piping for 2" and 3" lines only
• The wet tappable Model 3100 with either a thread-o-let fitting or saddle for 3" line sizes for flow meter installation and removal without having to shut down the process

For 4" and Larger Line Sizes

For Systems Which Can Be Shut Down

Model 2200 with either a thread-o-let or saddle fitting; the Model 2200 has a 1-1/2" NPT connection that can be retrofit to a 1-1/2" threaded bushing.



For Systems Which Cannot Be Shut Down

For systems which cannot be drained easily, where purging the air out of the system is difficult, or where maintaining flow is critical and the system cannot be shut down, the wet tappable Model 3100 is supplied with an isolation valve that is integrally mounted with the flow meter. The Model 3100 can therefore be inserted into and removed from a pipe under full-flow conditions. With the Model 3100, the use of bypass piping or isolation valves installed before and after the flow meter are not required.

To choose the appropriate Hydro-Flow model for your application, consider pipe size, how you will mount the flow meter on your pipe, your maximum process pressure and temperature, and whether or not you can depressurize the line to install and remove the flow meter. The table below highlights features of the five Hydro-Flow models. For more specific product information, consult the individual product specifications page.
