[0013] As used throughout this document, the word "cycle" has the same meaning as the word "stroke" when referring to pneumatic pumps; i.e., a pneumatic pump cycle and a pneumatic pump stroke refer to the same phenomenon.

[0014] Throughout this document, the pressure-reducing regulator may sometimes be referred to as a step-down regulator and / or as a filter regulator. Pressure regulators of this type are commercially available from various vendors.

[0015] As used throughout this document, the word "wireless" refers to any transmission of communication of radio signals in a frequency range of about 3 Hz to about 6 GHz. Examples of wireless communication routes include cellular and Bluetooth connections.

[0016] The invention is useful for pneumatic pumps used as subsurface fluid pumps, especially for example in pneumatic pumps that are associated with gas extraction wells, in particular for2PD.50397838.1Attv. Docket No. P-2112 PCT landfill gas extraction wells. The pneumatic pump cycle counters of the invention are also useful with pneumatic pumps that are associated with other types of subterranean wells.

[0017] The systems of the invention comprise one or more pneumatic pump cycle counters, each pneumatic pump cycle counter comprising a processing unit. Each processing unit is in electronic communication with a transmitter. Each such transmitter is in signal telecommunication with a data repository over a telecommunications network, preferably a wireless communication network, such as, e.g., the Internet via a cellular data service. As used herein, the term “transmitter” includes either a transmitter or a transceiver capable of sending and receiving wireless or cellular signals. While the systems of the invention include those with only one pneumatic pump cycle counter, generally a plurality of pneumatic pump cycle counters each are connected (preferably wirelessly) to a data repository (via operative telecommunication with a respective transmitter of each pump cycle counter). The pneumatic pump cycle counter in one aspect of the invention may comprise a pressure sensor in operative contact with air within an air inlet line of a pneumatic pump to generate pump cycle counts, and the pneumatic pump cycle counter in another aspect of the invention may comprise a pressure sensor in operative contact with air within an air exhaust line of the pneumatic pump to generate pump cycle counts. In a system according to one aspect of the invention, the pneumatic pump cycle counters may be all of the same type of pneumatic pump cycle counter (e.g., all having a pressure sensor on the air inlet line to generate pump cycle counts) or a mixture of different types of pump cycle counters (e.g., one or more having a pressure sensor on the air inlet line to generate pump cycle counts and one or more having a pressure sensor on the air exhaust line to generate pump cycle counts).

[0018] Each transmitter is configured to transmit signals, the signals indicative of a pump identifier and one or more pump cycle counts determined at a point in time or repeatedly determined over a time period. The pump identifier is often indicative of the pump's position or geolocation but could also be, e.g., a pre-assigned label, tag or serial number; preferably, the pump identifier is a pump position or geolocation. When other sensors are present, the signals may also comprise, as applicable, air inlet line pressure, the air inlet line pressure change, the air inlet line pressure changes over time, the ambient air pressure, the exhaust air pressure, the exhaust air pressure change, a time of measurement, a gas extraction well temperature, an ambient air temperature, a gas extraction well pressure, and / or a volume of liquid pumped. The transmitter is3PD.50397838.1Attv. Docket No. P-2112 PCT preferably configured to transmit signals via a wireless communication network, such as an internet connection and / or via one or more cellular networks.

[0019] The data repository stores signals after receipt from the transmitter. The signals comprise data representing a pump identifier and one or more pump cycle counts associated with and determined by the identified pump’s counter. When other sensors are present, the signals may also comprise, as applicable, air inlet line pressure, the air inlet line pressure change, the air inlet line pressure changes over time, the ambient air pressure, the exhaust air pressure, the exhaust air pressure change, a time of measurement, a gas extraction well temperature, an ambient air temperature, a gas extraction well pressure, and / or a volume of liquid pumped, all associated with the identified pump.

In still other preferred embodiments, the data repository is one or more cloud-based data storage systems and the data repository can be accessed via a webpage.
