Elster Meters Now Arriving!
Dear Valued Customers,
As many of you are aware, a number of our suppliers have been struggling with delivery times this past year, and in many cases we have had to work with 6 month deliveries on some of the most popular products we stock. We are delighted to announce that the AC250s you have all been waiting for are now pouring in and we are in the process of filling your back orders. Yesterday 720 AC250s showed up on our docks and we are already in the process of badging and proving them.
In addition, come July, we will have a healthy stock of meters available for you to purchase. If you know what you might need ahead of time, please let us know so we can set some meters aside and ensure we have what you need when you need it.

Sincerely,
Robert Barchard, General Manager - Barchard Engineering Ltd.

Product Spotlight
Mercury Instruments

Natural Gas, like all other gasses, is a compressible substance and has a density determined by its pressure, temperature and composition. When buying and selling gas, people want to know the quantity of (or amount of energy provided by) the gas they are purchasing, not the volume. Gas meters of all types are capable of measuring the actual volume of gas that flows through them, and then various correction factors need to be applied to account for the effects of pressure, temperature, and gas composition.
Approved instruments such as the Mercury Mini AT and the Mini-Max, can be placed on diaphragm, rotary, or turbine meters (with instrument drive) and can correct for live Temperature only, live Pressure and Temperature, or live Pressure, Temperature, and Super-compressibility.

Each month Barchard Engineering will answer a FAQ in hopes of providing you with accurate information that is relevant to your day to day business needs.
Q: "When is a PFM Regulator required?"
A: "In Measurement Canada’s inspection procedure, PFM installation is defined as a meter installation using an Approved Pressure Factor Metering Regulator to maintain an average meter pressure that exceeds the mean atmospheric pressure or the atmospheric pressure calculated, declared or measured, as the case may be, by more than 3.5 kPa in the International system of units or 0.5 psi in the Imperial system of units.
Also the Electricity & Gas Inspection Regulations, states that owners records shall contain … where the average meter pressure exceeds the mean atmospheric pressure or the atmospheric pressure calculated, declared or measured, as the case may be, pursuant to section 36 or 37, by more than 3.5 kPa in the International system of units or 0.5 psi in the Imperial system of units.
To summarize, PFM Regulators are required anytime there is over 1/2 psi in the meter (>14" w.c.) AND you don't have a Measurement Canada approved pressure corrector/instrument. "
If you have any questions that you would like answered, please feel free to contact us. We would be happy to provide a response to your question and may publish it in the next months newsletter.
