 VMRC - 2 Meters in 2 Years Study
The purpose of the study is to discover those combinations of seedling size, vegetation control, and fertilization that result in a two meter tall seedling in two years.
Two stock sizes, 2 vegetation control treatments, and 3 fertilizer treatments were tested for a total of 12 different treatment combinations (Table 4).
The 1 and 2 year fertilizer treatments did not differ because the second year fertilizer treatment had not yet been applied.

 Units: L
A lane meter is an area of deck one lane wide and one meter long, that is, 2 square meters (21.528 square feet).
Typically a lea of wool is 80 yards (73 meters); a lea of cotton or silk 120 yards (110 meters); and a lea of linen 300 yards (274 meters).
At sea, the lieue was often taken to equal 1/25 degree [2] or 2.4 nautical miles (4445 meters or 2.7619 miles); this unit was gradually replaced by the internationally recognized 3 nautical miles (5556 meters or 3.452 miles).

The role of Nabta as a regional ceremonial center is also indicated by a north-south alignment of nine large (average, 3 x 2 x 0.5 m) quartzitic sandstone slabs set upright about 100 m apart, and partially imbedded in playa sediments near the gathering area along the northwest margin of the seasonal lake.
Another 300 meters farther north of the calendar circle is a stone-covered tumulus containing the remains of a complete articulated young adult cow buried in a chamber that was dug into the floor of the wadi, surrounded by a clay collar, and roofed with limbs of tamarisk.
In the same area seven other similar stone tumuli containing the remains of cattle were excavated, but none of them had subsurface chambers; instead, the bones of the cattle, a few of which were still articulated, were simply placed among the stones.

 Industrial Water Meters
When the turbine of the CZWS series industrial water meter rotates on its shaft, it draws a small disc which, by means of a simple magnetic system, takes that movement to the dry part of the meter.
The industrial water meters output data as printable ASCII codes that are transmitted through an electric wire, which can be connected to other water meters, sent to an individual external reading point, or modem.
Taking advantage of this capacity, the industrial water meters can be joined together so that at one single point (the first or last meter or at a reading point) the user can extract totally error-free information up to 50 industrial water meters both quickly and safely (with a multiplexer up to 400 meters).

 Electro-Meters: Yokogawa 250 Series, Biglook meters
Meters are available in taut band or pivot and jewel elements.
The Big Look panel meters are gasketed to seal out dust and other air-suspended damaging particles and are ideal for adverse environments.
Pivot and jewel meters are recommended for high vibration environments because of the mechanism’s inherent stability and strength.

 2 buildings, one utility transformer, 2 meters, common g - Mike Holt's Code Forum
Both buildings are fed from a common utility transformer but each building is metered seperately (and have individual service entrance disconnects after the meters).
The plan would be to tie all the equipment grounding conductors (both service entrance panels and generator frame) together.
Unless the transfer switch switches the neutral, the generator cannot be SDS and 250.30 would not apply.

 Digital Panel Meters by Martel - FAQ - - Digital Panel Meters, Voltmeters, Ammeters, Digital Displays
All meters are calibrated and subject to at least one full functional check before dispatch, (in fact many are also subject to an extended burn-in), so it is extremely unlikely you could have received two faulty units.
Check also that the meter you are using does not have Digital Hold or Display Inhibit, in which case check that the voltage present on the Hold/Inhibit pin does not correspond with the level required to enable this function.
This is often characterized by the meter reading the correct value most of the time, but occasionally the reading jumping significantly, before resuming a constant level, or just general instability, or sometimes failing to fully zero, when the inputs are shorted.

 Hersey Meters - Residential Fire Meters
The RFM utilizes Hersey's unique vertical turbine measuring element to measure flow rates comparable to traditional positive displacement meters, yet provides a measuring element that allows suspend particulate matter to pass through the element unobstructed when emergency flow requirements for water are demanded.
Retro Thrust® rotor design extends the life of the meter by dividing wear between two points: during low flow the tungsten carbide thrust bearing floats against a sapphire bearing surface; during high flow the stainless steel shaft gently contacts a second sapphire bearing.
Electronic meters are distinguished by the red collar and lense terminal cover on top of the Translator® register.

 Some antennas for MURS and 2-meters
This page contains some VHF antenna designs for the 2 meter amateur (144.0-148.0 MHz) and MURS (151.82, 151.88, 151.94, 154.570, 154.6 MHz) bands.
While an amateur license is required to transmit on the 2 meter band, the MURS frequencies are unlicensed.
Although the FCC permits a maximum of 2 Watts (TPO) power output by a MURS transceiver, it places no limit to the gain of an external antenna attached to the radio.

 THE SLINGSHOT 2 METER ANTENNA RE-VISITED
It can be built as is for 2 meters, or you can try it on other bands or frequencies with the formulas provided by me below.
The completed antenna is bi-directional with a rough figure 8 pattern and is composed of 2, 3/4 wavelength sections of electrical conduit bent and cut to the lengths in the drawing and supported as shown on any type of insulating material attached to the mast with whatever arrangement of bolts, nuts, clamps, etc.
I had to change the spacing between the two elements to 1/2 inch and cut the short lengths to 19 1/4 inches and the long ones down to 39 1/4 inches and I came up with a 1.2 swr at 146.000mhz.

 2 meters - Elmers Forum at eHam.net
My guess is that you have some VERY high losses on 2 M and it is simply dissapating the returned energy in some fashion, thus showing a low SWR back in the station.
I have a 135' Center Fed Zepp that I use (by design) on 160 through 6 M and it does well on 6, but I have noticed some deep nulls in the pattern as would be expected on a wire with that many half waves on it.

Now we want to take the limit as n goes to infinity to find out when the distance between Achilles and the tortoise is zero.
Hence, we have - mathematically correct - computed that Achilles reaches the tortoise after exactly 2 seconds, and then, of course passes it and wins the race.
The tortoise runs 5 meters per second, and has an advantage of 10 meters.
