Watthour Meters for all your submetering needs!

Yosemite Watthour Meter — 120/240 volts Three-wire, 110-120 volts to neutral, 208-240 volts line to line.  Ninety percent of the watthour meters we sell are Yosemites.  This is the standard electric meter for homes, apartments, offices, and yachts.

Sequoia Watthour Meter — Single 120 volts Two-wire, 110-120 volts to neutral electric power meter.  Normally used to monitor a single circuit or a small boat in a marina.

Denali Watthour Meter — Dual 110-120 volts This is two Sequoia electric meters in one box.  Saves you a lot of money if you can use it.  Usually used in marinas where two small boats share the same power pedestal.

Olympic Watthour Meter A combination of the Yosemite and the Sequoia watthour meters.  Useful if you need separate measurements of 110-120 volt and 208-240 volt loads. Also used in place of Yellowstone in automatic reading systems where you want the power used by each phase.

Yellowstone Watthour Meter - 3 phase wye, 120/208 volts Four-wire, three phase wye, 110-120 volts to neutral, 208-240 volts line to line.  Normally used for air conditioners and other big motors.  If your building has this type of power, you should use this meter even if you only have 120 volt loads in the office you want to meter.

Zion Watthour Meter — 3 Wire, 3 phase delta, 208 volts  Three-wire, three phase delta, 208-240 volts line to line.  Use this only if you have a balanced load.  If a neutral is present in the panel, you will get a more accurate reading with a Yellowstone or Gettysburg meter if the load is out of balance.

Gettysburg Watthour Meter -  4 Wire, 3 phase delta, 120/208 volts  Four-wire, three phase delta, 110-120 volts to neutral on two legs, 208-240 volts to neutral on the third (wild or stinger) leg, 208-240 volts line to line.

Biscayne Watthour Meter — 220 Volts to Neutral  Two-wire, 200-250 volts to neutral.  The standard electric meter for Europe, Asia, Africa, and parts of South America.

Glacier Watthour Meter — 240 Volts Line to Line Two-wire, 200-250 volts line to line, no neutral. Normally used for appliances when a neutral is not present.  If there are any loads connected to neutral or ground, you will not get an accurate reading.

Lassen Watthour Meter - 3 phase wye, 277/480 volts  Four-wire, three phase wye, 240-280 volts to neutral, 440-480 volts line to line electric meter.  You can also use it with only one or two of the hot legs connected (for lights, heaters, small motors).

Shenandoah Watthour Meter - 3 phase delta, 277/480 volts Four-wire, three phase delta, 240-280 volts line to neutral on two legs, 440-480 volts on the third leg, 440-480 volts line to line.  Sorry, we don't make a three-wire, 480V delta.

Everglades Watthour Meter - Bi-directional Meter An experimental bi-directional meter intended for use with solar or wind-powered net metering systems.  The power flowing in one direction is displayed on one counter and the power flowing in the other direction is displayed on a second counter.  Works OK with one current transformer, but not with two or three.

The EZ Meter was originally designed to be mounted in power pedestals on the docks at recreational boat marinas and was originally sold without enclosures.  We now offer a growing line of enclosures for both indoor and outdoor use.  Any of the meters above can be installed in these enclosures.

The stainless steel mounting plate makes it easy to install the counter in an enclosure you provide. Just drill an inch and a half hole in the cover, snap the counter in the plate, put the counter through the hole, and drill four holes for #6 screws or pop rivets.

The NEMA1 enclosure is a triple-wide switch box with a custom made cover that holds the display counter and the meter.  There is no room inside for current transformers.  It is only available with the unsealed counters.  It is available with a standard switch box and with a box with a mounting bracket.

Four different sizes of plastic NEMA4X enclosures that hold from one to twenty four meters are available. Each size can be ordered in interior (clear or solid door) or exterior (solid door only) versions. The only difference between the interior and exterior versions is the type of plastic, the exterior version being UV resistant. These enclosures are usually mounted on a wall next to a breaker panel and the current transformers (CTs) are mounted in the breaker panel. There is adequate room in most enclosure for the CTs to be mounted inside, but consult the factory sales office to be sure. There is also room inside for battery powered radios that are part of a data collection system.

Each enclosure comes with a plastic panel that holds the meter and display. A screw is used to secure the cover on the smallest enclosure; a padlock secures the cover on the larger ones. NEMA4X meter enclosures that contain only meters that are 120 volts to neutral carry the CSA mark valid for the United States and Canada. CSA International has certified these meters after they were tested against the UL/CSA/IEC 61010-1 standard.

The 6" x 6" x 4" enclosure holds one or two meters.

The 11" x 7" enclosure holds up to 4 meters.

The 13" x 13" version holds up to 8 meters.

the 19" x 15" version hold up to 12 meters on one panel or up to 24 meters on two panels.
