2A brief history of Swain and Operational Procedures The Swain Meter Co.A brief history of SwainandOperational ProceduresThe Swain Meter Co. is located at 1611 S. Isabella Road, Mt. Pleasant, Michigan 48858We manufacture a one-of-a-kind, world renown, DC ammeter used in a wide variety of industries both onshore and offshore applications.ByScott Miret 10/7/08
3William H. Swain founded the company in 1965 Bill Swain founded the William H. Swain Co. in Sarasota Florida back in Previous to this Bill was employed in various roles with the US military and NASA – working on guidance systems for rocket and advanced marine navigation tech for that time period.Bill Pictured second from left
4Development of the SWAIN METER Pictured below are some of Swain’s first analog ammeters.In Bill Swain developed the first DC Clamp-on Ammeters. These durable and accurate instruments were created to help pipe line operators monitor cathodic protection (CP) current flow on their lines.Used in a wide variety of industries all over the world, Swain meters measure the magnitude and direction of current on conductors.From the beginning Swain meterswere used not only as portable DC and AC current measuring devices, but as permanently installed instruments on buried pipelines both on-shore and in sub-sea applications.The uniqueness of the Swain Meter is the same today as it was 43 years ago when Bill built his first meter. This DC Clamp –on ammeter is Still the only one of its kind in the world today.
5The next 40 yearsIn the mid 1980’s Swain meters were fitted with digital LCDs. The technology remains basically the same while the meter face becomes more streamlined and user-friendly.
6Swain Meter evolvesLater models of Swain meters in the 90’s and 2000’s still use the bullet-proof and patented technology. These later models have digital LCD’s and further simplified controls.Swain meters are manufactured in 2 models – The MER Meter (pictured left) has a “manual” Zeroing knob and Range select switch.
7Swain Meter evolvesThe second meter we call the “AUTO MER”. This features Auto- Zeroing and AutomaticRanging from 0 – 2.0 Amps, 0 – 20 Amps &0 – 200 Amp ranges.Both MER and AUTO MERMeters have data outputJacks.MER is a Bill Swain coined term meaning “Magnetic Error Reduction”. A key benefit to Swain Meter’s accuracy it the ability to Zero-Out the earths magnetic field thus giving a true measurement of DC Current. The Swain Meter also cancels out AC Interference upwards of 10-Amps to again provide the user with accurate DC current measurements.
8The technology that drives the Swain Meter has changed little in over 40 years. Yet the switch from Analog to Digital technology has greatly increased the efficiency of the manufacturing and calibration processes.The wrench and space shuttle are not part of our new circuitryOld SchoolNew School
9Swain Clips & ClampsSwain Clips & Clamps are precise and sensitive instruments that form a 360` closed loop around a conductor.Swain Clips and Clamps are also referred to in literature as “Sensors” connect to the MER meter.Swain Sensors are rugged, hand crafted instruments that work in harsh environmentsSwain clips and clamps connect to the Swain Meter and detect DC currents from 5-mA to 200+ Amps. Direction of current is etched onto the clip or clamp.
10Clips & Clamps come in many sizes Clips are hand held, spring loaded sensors for quick readings on conductors.Clips are built from 3/4” in diameter through 6” in diameter.Clips shown to the right are sizes: Mini-Clip (no longer built), 3/4”, 1.5”, 2.5”, 4” &6”.
11Swain Clips & ClampsClamps are sensors made in 2-half circles that go aroundConductors then held together with Nuts to form a circle.Clamps are built in diameters beginning at 6” through 82”.Clamp diameters from 60”on up are built in 4 sections.Swain Clamps are coated with a rock-hard epoxy that withstands decades of rough usage. Clamps are permanently installed around pipelines in the
12Larger Clamps Clamp Construction 42” Clamp It takes many days to weeks to build each large clamp. Each step of the process to build clips and clamps was perfected by Bill Swain decades ago. Little changed to date.42” Clamp
13Larger diameter clamps must be manufactured in 4 pieces Larger diameter clamps must be manufactured in 4 pieces. This clamp is being assembled for a field test prior to shipping.82” MER 2 ClampClamp is constructed in 4 Sections
14Our largest to date – 82”This 82” Clamp was sold to Water Care Services in Auckland New Zealand in Summer 07’Clamps of this size usually require their own AUTO MER meterEach Swain Meter is “Calibrated” precisely to “One” clip or clamp. Additional clips or clamps that accompany a meter have a “Calibration Factor” tagged to the meter cable. Some users have 6 clips and clamps per Swain meter. We recommend larger clamps get partnered to their own specific meter because there are additional electronic components needed to support these big hoops.

Swain Co., finally retired at the age of 80 and sold his company.It was purchased by a Mt. Pleasant, Michigan USA based company and became The Swain Meter Co.
18What IS a Swain Meter?Precision built and calibrated instrument, coupled with clips or clamps, used to measure magnitude and direction of current flow.Swain meters are used today in most all countries on the planet.

26Refineries use Swain meters to precisely measure current distribution and to see if insulating flanges are working. Individual cables in rectifiers are measured with accuracy as are banks of pipes and cables in close proximity
28Using the MER MeterThe Swain meter is a precise instrument that measures DC current from 5-milliamps to 200 Amps with a + /- 1% accuracy.The meter measures with a1-milliAmp resolution in the 0 – 2 Amp Range10-milliAmp resolution in the 0-20Amp Range100-milliAmp resolution in the 0 – 200 Amp RangeThe meter will cancel out up to a10-Amp AC interference - this designed to maintain accuracy with DC measurements
29Using the MER Meter Connect the Clip or Clamp to the Swain Meter Turn the On/Off Switch to the “ON” positionTurn Range Select to 2AHold the Clip or Clamp 6 inches away from the conductor, oriented so the plane of the clip/clamp intersects the conductor at a right angleHold the Clip/Clamp stillAdjust Zero knob until LCD reads Zero*(You have successfully canceled the earth field reading)Place clip/clamp on conductor and observe readingIf current exceeds 2-Amps and “Over Range” message appears on LCD – Turn Range knob to 20A or the 200A position
30Using the MER MeterCurrent direction is indicated by either the presence or the absence of a “Negative”Sign the left of the numbers on the LCDThe current direction Arrow is etched onto the sides of all clips and clamps.Take a reading with the clip/clamp in one direction then flip-it 180` and notice the appearance of the Negative sign.*Current direction is always flowing in the positive clip/clamp orientation
32Using the AUTO MERThe Swain meter is a precise instrument that measures DC current from 5-milliamps to 200 Amps with a + /- 1% accuracy.The meter measures with a1-milliAmp resolution in the 0 – 2 Amp Range10-milliAmp resolution in the 0-20Amp Range100-milliAmp resolution in the 0 – 200 Amp RangeThe meter will cancel out up to a10-Amp AC interference - this designed to maintain accuracy with DC measurements
33Using the AutoMER Connect the Clip or Clamp to the Swain AutoMER meter Hold the Clip or Clamp 6 inches away from the conductor, oriented so the plane of the clip/clamp intersects the conductor at a right angleHold the Clip/Clamp stillTurn the On/Off Switch to the “AUTO” position. Wait several seconds until the “Ready” light comes on*(You have successfully canceled the earth field reading)Place clip/clamp on conductor and observe readingIf current exceeds 2-Amps the AutoMer meter automatically changes ranges to the 20A range or 200A range
34Using the AutoMER in Manual Mode Turn On/Off Switch to “Manual” ModeHold clip/clamp steady near conductorZero meter using the “Zero” knobPlace clip/clamp onto conductor and take reading*To manually change ranges, turn On/OffSwitch from “Manual” to “Off” for a split second. Note the LCD decimal point shifts one position to the right . Repeat to change ranges again.Example of LCD positions:.000 = 2A Range0.00 = 20A Range00.0 = 200A Range
