What does aecv mean on a gas tank?
A.E.C.V. Definition. Alternative Emergency Control Valve. A valve which is NOT the ECV but is intended to be used by the customer to shut off gas in an emergency. Popular.
What is an ECV on a gas meter?
Every gas pipe installation and meter should have one. The ECV is situated where the gas network or gas transporters pipe meets the gas meter. Its purpose is to control the flow of gas where it should be switched off in the event of an emergency / gas escape, or where there is no gas meter installation already in place.
What is a 6m aecv?
The 6m dimension is from the MCV to the point of entry to the building, ie the door, it's about the person being able to get from their house to the MCV to turn the gas off, so if the meter box is more than 6m from the door there needs to be an AECV where the gas pipe enters the property, not necessarily where the door is if that makes sense!!!!!!!
What is an emergency control valve (ECV)?
An Emergency Control Valve (ECV) is a safety mechanism on a gas service pipe connecting a gas meter to the gas mains. Every gas pipe installation and meter should have one. The ECV is situated where the gas network or gas transporters pipe meets the gas meter. Its purpose is to control the flow...
What does ECV stand for gas?
Calorific value (CV) is a measure of heating power and is dependent upon the composition of the gas. The CV refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions.
What is a primary gas meter?
Primary Meter . ( 主錶) means a meter connected to a service pipe for ascertaining the quantity of gas supplied through such pipe, but does not include a secondary meter; Sample 1.
How many types of gas meters are there?
There are four natural gas meter types often used for flow measurement. They are mass flow meters, velocity flow meters, differential pressure, and PD meters.
What is a secondary gas meter?
“secondary meter” means a meter, other than a primary meter, for ascertaining the quantity of gas provided by a person for use by another person.
What is an ECV gas meter?
An Emergency Control Valve (ECV) is a safety mechanism on a gas service pipe connecting a gas meter to the gas mains. Every gas pipe installation and meter should have one.
Where is the ECV wheel?
The ECV is normally positioned within two metres of the gas meters or within visual sight of the meter.
What is the purpose of a gas meter?
Its purpose is to control the flow of gas where it should be switched off in the event of an emergency / gas escape, or where there is no gas meter installation already in place. Occasionally some, older installations may have a missing or corroded valve.
What is the maximum amount of gas that an u16 meter can pass?
A U16 is a tiny diaphragm meter that is often used in business settings but may also be utilized in residential settings. All Diaphragm Gas Meters have a U number that corresponds to the meter capacity in Standard Cubic Metres per Hour (SCMH). As a result, an U16 meter has a 16 cubic meter per hour capacity.
Is it possible to buy an u16 gas meter?
A u16 is typically used in bigger household meters and small commercial buildings. It isn’t just a ‘business gas meter.’ I have a few clients that want a little more than an u6 metre can provide. They usually feature two boilers, such as a range stove and a gas fireplace.
What exactly is an AECV gas?
Valve for cutting off the supply of gas in an emergency, not an extra emergency control valve (AECV), designed for use by a gas customer and positioned at the end of a service or distribution main. The ECV’s output marks the end of the Network and hence defines it.
What is the purpose of a gas sub meter?
Utility submetering is a billing method that enables a landlord, property management company, condominium association, homeowners association, or other multi-tenant property to charge renters for individual utility use. Individual water meters, gas meters, or electricity meters are used in this method.
What is an u6 meter, exactly?
The U6 and SC6 meters have a measurement unit with a cyclic volume of two litres that is intended to. In all natural gas and LpG applications, correctly meter quantities.
How do gas meters get their power?
A Smart Meter calculates the amount of power consumed in a half-hour period by sensing the electrical current flow and voltage at regular intervals. The flow of gas is also monitored at regular intervals. This data may be provided to your In-Home Display as well as your provider.
Is it true that gas meters control pressure?
The customer is responsible for any equipment and gas supply pipes downstream of the home meter. When the gas reaches the meter of a client, it travels through another pressure regulator, which reduces the pressure to under 14 pounds if required. Some service lines transport gas that has already been compressed to a very low pressure.

I went to a job the other day to service a fire, its in a large house that has been turned into flats, this flat is on the ground floor just off the foyer, the gas meter also serves 2 or 3 of the flats upstairs and is situated just inside the front door in a cupboard.

I would think the measurement was from the door to the premisses as it would be deemed 6m is the maximum safe distance a person should travel to isolate the gas in an emergency.

What is the mains gas pressure?
Distribution systems run at substantially lower pressures than transmission pipes, which may reach over 1000 psi. Some gas mains in a distribution system (2 to 24 inches in diameter) may reach 200 psi, while the little service lines that feed gas to individual residences normally function at less than 10 psi.
At the meter, what should the gas pressure be?
Most meters should have an operating pressure of between 19 and 23 mbar. This meter’s pressure is 20 mbar, thus no more action is required. If the gauge reading is outside or within this range, however: Contact your gas provider if your meter is a main meter.
What is the working pressure of a high-pressure gas line?
The ‘highways’ of natural gas transportation are interstate pipelines. Natural gas carried via interstate pipes is conveyed at high pressure, with pressures ranging from 200 to 1500 pounds per square inch (psi).
What is the purpose of a gas tightness test?
A full gas safe inspection includes a gas tightness test, which evaluates the gas pressure within a property’s pipework. It will verify that the system is free of gas leaks.
What does it mean to be under pressure at work?
The typical operating pressure at which a component is intended to function with a safe margin below the point at which the material may yield or explode. Also known as maximum working pressure or design working pressure.
What exactly is an AECV gas?
Valve for cutting off the supply of gas in an emergency, not an extra emergency control valve (AECV), designed for use by a gas customer and positioned at the end of a service or distribution main. The ECV’s output marks the end of the Network and hence defines it.
When the gas pressure is too high, what happens?
If the gas pressure on the side of the gas train is too high, it might cause the unit to overheat. Similarly, too much pressure on the intake side of the valve will result in gas valve failures or no heat since the valve will not open against “high pressures.”
