Abstract
A method of distributing liquefied petroleum gas is described. The method comprises receiving payment for a predetermined amount of liquefied petroleum gas, transmitting an instruction to a valve to distribute liquefied petroleum gas monitoring, by a metering device, an amount of liquefied petroleum gas distributed determining, by the metering device, that the amount of distributed liquefied petroleum gas has reached a threshold amount, wherein the threshold amount is based, at least in part, on the predetermined amount, and responsive to determining that the amount of distributed liquefied petroleum gas has reached the threshold amount, transmitting an instruction to the valve to cease distribution of the liquefied petroleum gas.
Claims40
A method of distributing liquefied petroleum gas comprising:
- receiving payment for a predetermined amount of liquefied petroleum gas;
- transmitting an instruction to a valve to distribute liquefied petroleum gas;
- monitoring, by a metering device, an amount of liquefied petroleum gas distributed;
- determining, by the metering device, that the amount of distributed liquefied petroleum gas has reached a threshold amount, wherein the threshold amount is based, at least in part, on the predetermined amount;
- and
- responsive to determining that the amount of distributed liquefied petroleum gas has reached the threshold amount, transmitting an instruction to the valve to cease distribution of the liquefied petroleum gas.
A system comprising:
- a tank configured to store a volume of liquefied petroleum gas;
- a metering device, wherein the metering device measures an amount of liquefied petroleum gas used by a consumer;
- and
- a valve, wherein the valve is configured to control flow of the liquefied petroleum gas from the tank and to close responsive to the metering device measuring that a predetermined amount of liquefied petroleum gas has been provided from the tank.
A method comprising:
- receiving a payment for a predetermined amount of liquefied petroleum gas;
- providing liquefied petroleum gas to an appliance;
- metering an amount of liquefied petroleum gas provided to the appliance;
- determining that an amount of distributed liquefied petroleum gas has reached the predetermined amount;
- and
- ceasing to provide liquefied petroleum gas to the appliance.
A method of distributing liquefied petroleum gas comprising:
- attaching a valve to a liquefied petroleum gas tank comprising a predetermined amount of liquefied petroleum gas;
- monitoring, by a metering device, an amount of liquefied petroleum gas leaving the tank;
- determining, by the metering device, the amount of distributed liquefied petroleum gas remaining in the tank, wherein the amount remaining is based, at least in part, on the predetermined amount;
- and
- transmitting, to a receiver, the amount of liquefied petroleum gas remaining in the tank.
A system for monitoring the amount of LPG in a tank comprising:
- a tank configured to store a volume of liquefied petroleum gas;
- a metering device, wherein the metering device measures an amount of liquefied petroleum gas removed from the tank by a consumer;
- and
- a valve, wherein the valve is configured to control flow of the liquefied petroleum gas from the tank and to close responsive to the metering device measuring that a predetermined amount of liquefied petroleum gas has been provided from the tank.
A method of monitoring the amount of gas in an LPG tank comprising:
- connecting a tank of LPG containing a predetermined amount of liquefied petroleum gas to at least one appliance;
- providing liquefied petroleum gas from the tank to the appliance;
- metering an amount of liquefied petroleum gas provided to the appliance;
- determining the amount of LPG remaining in the tank;
- and
- storing a value or percentage of the amount in a memory device.
