Reading a Hydrometer Register
Standard Register
Total Flow is calculated by adding the readings from the Totalizer and the three fractional dials. The three fractional dials measure quantities smaller than the totalizer reading and are continuously turning while calculating the flow.
Totalizer Reading
Rotates sequentially for each 1000 U.S.G. (U.S. Gallons) calculated Number displayed is multiplied by 1000 to reach total U.S.G.
Fractional Dial 1 (right dial) Each number (1-9) on the dial is multiplied by 100 to reach U.S.G. One complete revolution on this dial = 1000 U.S.G.
Fractional Dial 2 (lower center dial) Each number (1-9) on the dial is multiplied by 10 to reach U.S.G. One complete revolution on this dial = 100 U.S.G.
Fractional Dial 3 (left dial) Each number (1-9) on the dial is multiplied by 1 to reach U.S.G. One complete revolution on this dial = 10 U.S.G.
Register Electrical Output
Netafim USA Hydrometers are equipped with electrical output devices which combine the high reliability of hermetically sealed, magnetically driven registers with electric transducer output options.
Applications
For automation and communicating with controllers and other devices Where more than just the traditional register is required
Features & Benefits
Equipped with electrical output devices Combines high reliability of hermetically sealed, magnetically driven registers with a wide variety of electric output options Magnetic registers can be easily changed to accommodate a variety of electrical outputs
Available Register Options
Netafim USA has three types of transducer outputs available which provide three levels of resolution:
- Reed Switch (RS) Register - low frequency pulse output for functions related primarily to recording volume.
- Photo Diode (PD) Register - standard frequency pulse output (open collector) for functions such as rate of flow and recording total volume.
- Photo Diode (PDH) Register - high frequency pulse (open collector) for functions such as rate of flow and recording total volume.
