SADDLE METER OPERATION
MAGNETIC
COUPLING
The double magnetic transmission of the Saddle Meter along
with repelling magnets ensures accurate measurements.
Transmission gears are located in a sealed, dry compartment
which has no contact with the water - only the impeller
contacts the water. The balanced impeller has an equal
load on the front and rear bearings preventing wear and
maintaining high accuracy. Injecting fertilizers and chemicals
through the system will not damage the non-corrosive
components of the Saddle Meter.

STRAIGHT PIPE INSTALLATION REQUIREMENTS





Straight Pipe Installation Requirement: 10 x diameter pipe upstream (before the meter) and 5 x diameter pipe downstream (after the meter).
The saddle meter may be installed in any position. For non-horizontal positions, the flow should be upwards.
Prior to installation of the meter, the pipeline should be thoroughly flushed.
Meter must be installed so that the pipe is full of water at all times during metering.
Recommendation: Continuous Acting Air Vents of proper size and type be installed to eliminate air.

ORDERING EXAMPLE:
36SM6ER11EEFXX.XXXX
6” Saddle Meter, ER Register,
Volume in Gallons, Flow Rate in Gallons
per Minute, Pulse Output 1 is 10 Gallons
per Pulse, Pulse Output 2 is 10 Gallons
per Pulse, Forward Flow Direction,
Inside Pipe Diameter (to be specified)
I = 0.001 AF PER PULSE
J = 0.01 AF PER PULSE
K = 0.1 AF PER PULSE
* Pulse rate is based on volume units.
If volume is in Acre Feet and Option D is chosen for
Output 1 or 2, it will result in 1 pulse every acre foot
of water that passes through the meter.
To convert Acre Feet to Gallons per Pulse,
multiply by 325,850.
INDUSTRY'S LONGEST WARRANTY
Netafim stands behind our water meters with an unprecedented
warranty - the industry's longest - three (3) years on the metering
