GENERAL DESCRIPTION
A hydrometer combines a hydraulic master valve, water meter and a
flow sensor in a single unit. Netafim USA’s Hydrometer is designed
for high pressure, remote control irrigation and industrial applications.
Body: Horizontal
Available Sizes: 1½”, 2”, 3”, 4”, 6” and 8”
Operation: For automatic and remote operation in a variety
of applications. Remote operation is possible via
an external solenoid valve activated by a remote
controller or control center. Flow rate and volume
data are electronically transmitted to the remote
controller by means of a transducer inserted into
the register dial.
WATER METER/REGISTERS
The hydrometer contains both a dry contact (reed switch) type
magnetic drive and a higher frequency output photo-diode register
transmission water meter, the impeller is the only moving part in
contact with the water. The meter may be calibrated to measure either
gallons or cubic meters. A hermetically sealed register contains the
dial face and all mechanical meter components.
The dial face contains:
• Totalizer
• Three (3) analog pointers
• Rotating flow indicator or leak detector
A magnetic pointer, located over one of the analog pointers, measures
the flow rate and transmits the data to the reed switch transducer in
the register cover.
HYDRAULIC VALVE (FLOW SENSOR)
The hydrometer contains a hydraulic master valve operated either
manually or by remote control. The valve normally remains closed
until a command is received to open it. Hydraulic commands
are transmitted to the valve via an external solenoid valve. The
hydrometer can also be ordered in a Normally Open configuration.
In this case the valve is opened until a command is received and the
valve closes.
