I believe it depends on what kind of flow meter you are looking for. They can range from 19.99 and go up. The more expecive it gets the better the flow meter.

The orifice meter is used with the orifice flow rate meter and measures things like the flow rate of natural gas. It can measure other things and companies use it for different things also. Some companies give lessons or classes in using the orifice meter.
1 meter is about 1 yard and 3 inches or about 39 inches
Your electric utility company has a meter department capable of answering this. There are usually pictures of the meter dials/digits included in teaching someone to read the meter, so this is not a good forum to do so. If your electric company does not have the meter in question, find out the manufacturers name, and your utility meter department may help locate a contact at the manufacturer for you. Usually, residential meters have a hot sheet typed up showing how to read them, and the utility will simply mail it to you or possibly scan/fax it.
liters per minute
A reading on an oxygen flow meter is typically taken from the flow meter itself where the indicator or marker aligns with a specific number indicating the flow rate of oxygen in liters per minute. It is important to read the measurement at eye level to ensure accurate readings.
THE SYMBOL FOR Flow Meter is : FI as Flow Indicator
The flow would be 2.5 with a meter with 12 inch diameter. This is with a flush at 5.0 FPS.
The above is the symbol of flow meter.
Yes, a water meter will run backwards. Running your meter backwards is stealing and could result in your service being diconnected and or a fine. Modern meters that are read via radio signals are sofisticated electronic instruments and will report leaks and reverse flows when read. So if your meter is a radio read type you had better not mess with it.
One can recalibrate a flow meter by having a company or owning a flow meter supplier or using a flow meter lab. No matter what type of flow meter they need to be checked to see if they need to be recalibrated regularly.
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
The flow range of a gas flow meter is the range of flow rates that the meter is capable of measuring accurately. It typically includes a minimum and maximum flow rate that the meter can reliably detect and measure. It is important to ensure that the flow rates being measured fall within the specified flow range of the gas flow meter for accurate readings.
The easiest way to find out how to read water flow meters, is by checking your local government or water provider's website. On the majority of these websites there is an explanation for how to read your meter.
An amp meter measures current flow, not power. An amp meter measures instantaneous current either by being inserted in series with the wire being measured for current flow, or clamped onto a single current carrying wire and measuring current flow by induction. If the load is disconnected then no current will flow and the amp meter will read zero.CommentThe correct term is ammeter, not 'amp meter'.
