THE METER OF CHOICE
The Cadillac® Magnetic Flow Meter has been acknowledged as the industry standard for accuracy and installation flexibility
THE METER OF CHOICE FOR WATER AND WASTEWATER APLLICATIONS
The Cadillac® CMAG magnetic flow meter is a rate and totalizing device, which is capable of measuring liquids of all types and consistency while providing an obstruction free flow path. Due to it's unique flow tube/coil design, it is particularly suitable for new or retrofit Water and Wastewater applications. Employing a unique coil winding pattern and containment/focusing plates the Cadillac magnetic flow meter does not require any flow profiling or piping straight run while still meeting the stated meter accuracy (+/-0.25% of rate). In any conductive liquid application the Cadillac® magnetic flow meter is the number one technology choice due to Cadillac®'s accuracy, linearity, reliability and rangeability.
Like many other volumetric flow meters, the Cadillac® magnetic flow meter is a velocity measuring device which computes flow by multiplying the effective cross sectional area of the flow meter with the detected fluid velocity. The meter has no moving parts and consists of a meter body with encapsulated coils, electrodes and an amplifier assembly. It detects velocity by measuring an induced voltage that is developed by moving the conductive fluid through a magnetic field.
The Water / Wastewater Industry Standard
With the introduction of the magnetic flow meter in the early 1970's it has been a favorite choice for the Wastewater marketplace, due to it's full bore design, no moving parts, and ability to operate in heavy fouling applications. With increased wetted material selections most Water, including potable, applications have also looked to magnetic flow meters as the preferred choice, especially in applications requiring analog (rate) or pulse (totalized) outputs.
APPLICATIONS:
- Data Source for energy management system, DCS, district-wide systems.
- Cooling tower Water flow.
- Potable Water flow.
- General industrial and domestic Water flow.
- Industrial and domestic Wastewater flow.
- Aquifer injection Water flow.
- Process Water flow.
- Water based Coolant flow.
- Water based Slurry flow.
- Reclamation Water flow.
- Clarifier Water flow.
FEATURES:
Accuracy
+/-0.25% of the reading for liquids. High accuracy allows significant improvement
in both measurement and customer billing.
Rangeability
Typically 300 to 1 turndown or better. With seasonal heating/cooling load variation, the need for a large turndown is essential. Cadillac® magnetic flow meters will accurately measure all load requirements with proper sizing.
Longevity
Mean time between failure (MTBF) of 75 years. With no moving parts and through
simple robust design the meter has unmeasured life expectancy.
Modern Electronics
Meeting the challenges of the next millennium. Meters are equipped with
electronics capable of registering locally, remotely or interfacing with
an energy management system. Built to withstand the toughest conditions.
Flow Profile Independent
The flow meter does not require any flow conditioning or piping straight run as required with other volumetric flow meters. Piping straight run from the centerline of the meter is 1.5 pipe diameters, which is essentially the mating flange face of the piping system
PRINCIPLES OF OPERATION
 |
 |
Faraday’s law states that, when you move a conductor perpendicular
through a magnetic field, a voltage will be induced proportional to the velocity
of the conductor. A magnetic field is created by a set of coils which are
encapsulated and rigidly retained in the meter flow tube and, when a conductive
liquid moves through that magnetic field, a pair of electrodes measures the
voltage induced by the movement of the liquid. The measurement is independent
of conductivity changes in the liquid as long as it remains above the minimum
threshold of 3 uS/cm2.
The relationship between the liquid velocity and the induced voltage is expressed in a meter K-factor. The meter K-factor is unique to each and every meter and is documented during a NIST traceable flow test completed prior to shipment. With the K-factor established a highly accurate volumetric flow is calculated by multiplying the cross sectional area of the flow tube by the measured liquid velocity. This volumetric relationship can then be converted to various engineering units and the flow meter converter can then retransmit this information with a 4-20 mA current signal and/or conditioned pulse. An optional integral LCD Indicator/Totalizer is available to locally display and totalize in whatever engineering units preferred.

INSTALLATION
Installation requirements have been redefined with the Cadillac magnetic flow meter. Employing coil and plate shaping techniques the Cadillac® meter provides a uniform magnetic flux distribution within the flow tube, allowing the meter to measure and sample uniformly the entire flow tube area. In addition, the electronics provide high frequency DC square wave signal generation and flow signal sampling, enabling fast response to turbulent or tumbling flow conditions.
In practice, this means the Cadillac® magnetic flow meters do not require
piping straight run or flow conditioning, and may be installed next to elbows,
tees, valves, etc. without any effect in meter accuracy or stability (see
Illustrations below).
In comparison, the straight pipe run requirements for all other magnetic
flow meters are as follows:
Downstream of the meter:Expander (2-5) diametersTee - (2-5) diameters Elbow - (2-5) diameters Valves - (2-10) diameters |
Upstream of the meter:Expander - (10) diametersTees - (5) diameters Elbow (5) diameters Valves - (10) diameters |
| (see Illustrations below) | |
Unlike other technologies such as turbine, variable orifice, pitot tube, orifice plates/DP cells, and Vortex, including the Cadillac® Vortex flow meter, magnetic flow meters do not have a low flow cutoff, essentially allowing the meter to read to zero. With such a wide flow range capability for the technology, most applications can be addressed with meters at full line size.

FLOW METER SIZING INFORMATION
The Cadillac® magnetic flow meter has a 304 stainless steel body and
is always sold with grounding rings installed. The primary reason for providing
grounding rings is to contain the magnetic field within the meter body and
to assure the liquid potential is grounded properly. As a consequence, the
induced voltage is remarkably free of noise allowing the meter to reliably
measure extremely low fluid velocities. The table below lists minimum as
well as maximum flow ranges for each meter size, in GPM for liquids and lbs/hr
for condensate.
