Definitions

  • a utility company provides water and/or gas to clients through a network of pipes as part of an overall distribution system. In order to do so, the utility company requires information about the water and/or gas flowing through the pipes. This implies a continuous supervision of the system to maintain normal operation, and at the same time, to indicate warning status or alarm conditions.
  • the pipes have theretofore been coupled to a sensor. Due to the location of the pipes, which are commonly buried underground, the sensor is typically permanently installed.
  • a device comprises a saddle mountable on an outer circumferential surface of a pipe, a sensor valve connected to the saddle, a flushing valve vertically connected to the sensor valve and connected to the saddle, and an operating assembly connected to the sensor valve and the flushing valve, wherein the operating assembly is configured to open and close the valves independently.
  • a device provides or denies access to the pipe by opening or closing the sensor and flushing valves, respectively.
  • This configuration can allow for conveniently and easily providing various sensors or other devices when needed in a compact package, as well as accessing and easily removing the sensors or devices (e.g., for maintenance, replacement) from the ground.
  • This can also allow for drilling a hole in the pipe under pressure as the flushing valve can allow for the fluid under pressure to exit the assembly without flooding the housing interior.
  • the device further comprises a housing extending longitudinally and connected to the saddle.
  • the housing provides a channel with which to access a pipe buried beneath a ground surface and further provides protection to the enclosed component parts.
  • the vertically extending housing has a compact cross-section, but still allows for easy access to the pipe and other components within the assembly.
  • an interior of the housing is open to an interior of the pipe when the sensor valve is open. This allows the interior of the housing to be in communication with the interior of the pipe.
  • the height of the housing is adjustable.
  • An adjustable housing provides access to a pipe buried at any level beneath the ground surface by forming a channel extending from the ground surface to the pipe.
  • the housing is telescopic such that the height of the housing is adjustable.
  • a telescopic arrangement provides easy adjustability of the housing, and is particularly convenient for adjusting to pipes at different levels in the ground.
  • the telescopic arrangement further prevents forces generated by heavy objects being placed on a top portion of the housing at or near a ground surface, such as a meter pit, from being transferred to the pipe.
  • the sensor valve and the flushing valve comprise a T-tube.
  • the T-tube provides access to the valves by the operating assembly.
  • the operating assembly comprises a tool.
  • the tool enables the operating assembly to open and close the valves.
  • the tool rotates around a fixed point connected to the saddle. This enables the tool to easily open and close the valves. Opening or closing the sensor valve thereby provides or denies access to the pipe.
  • the device further comprises one or more additional valves. Additional valves can also be vertically stacked and can provide seal reinforcement at the interface to helps to ensure that liquid or gas flow remains in the pipe when desired and does not enter the housing.
  • the flushing valve comprises a one-way valve.
  • the one-way valve relieves pressure and releases excess liquid or gas from housing.
  • the flushing valve can further comprise a hose for easily transporting the excess liquid or gas from the housing while keeping the water line clean (especially useful for drinking water lines), and protecting the line from sand and/or other contaminants.
  • the device further comprises a sensor. This allows the sensor to sense at least one property of liquid or gas within the interior of the pipe.
  • a sensor assembly comprises a sensor, a saddle mountable on an outer circumferential surface of a pipe, a housing extending longitudinally and connected to the saddle, a sensor valve connected to the saddle, a flushing valve vertically connected to the sensor valve and connected to the saddle.
  • a tool which is connectable to the sensor valve and the flushing valve can be used to open and close the valves from a ground level.
  • the tool facilitates alignment of the sensor with the hole in the pipe.
  • the tool further facilitates positioning of the sensor from a stationary position to a retracted and/or sensing position, and back.
  • the sensor is vertically moveable between a retracted position within an interior of the housing and a sensing position within an interior of the pipe.
  • Such an assembly enables the sensor to easily access the interior of the pipe. This can allow for conveniently and easily providing various sensors or other devices when needed, as well as easily removing the sensors or devices (e.g., for maintenance or replacement) from a ground level.
  • the housing can only be placed in one position thereby ensuring the sensor is placed in the correct position within the pipe relative to the flow direction of the liquid or gas.
  • the pipe is located below a ground surface.
  • a utility company such as a water utility company or a gas utility company.
  • the senor is configured to sense at least one property of liquid or gas within the interior of the pipe. This allows the sensor to provide an indication of normal operation, warning status or alarm conditions.
  • the assembly further comprises a communication device. This allows the sensor to sense at least one property of liquid or gas within the interior of the pipe and relay the data to the communication device, which may receive, process, store and further relay the data.
  • the communication device and the sensor are electrically coupled. This enables the relay of data between the communication device and the sensor.
  • the communication device is mounted on a top portion of the housing. This allows the communication device to be at or near the ground surface and further allows the communication device to relay data from the sensor to a server using a network.
  • a method of operating a sensor assembly comprises introducing a sensor into a housing, opening at least one valve, introducing the sensor at least partially through the at least one valve and into an interior of the pipe and sensing at least one property of liquid or gas within the interior of the pipe.
  • the method further comprises relaying data from the sensor to a communication device.
  • a communication device This allows the sensor to sense at least one property of liquid or gas within the interior of the pipe and relay the data to the communication device, which may receive, process, store and further relay the data.

  • liquid or gas within the pipe 105 is prevented from flowing out of the pipe 105 to the interior 140, 165 of the housing 135, 155.
  • the sensor 1 15 senses a property of liquid or gas within the interior 1 10 of the pipe 105 and relays the data to the communication device 150, which may receive, process, store and further relay the data.
  • the sensor 1 15 can sense any property of liquid or gas including, but not limited to, temperature, pressure, flow rate, density, conductivity, pH or viscosity.
  • the sensor 1 15 can also sense any property related to the pipe 105 including, but not limited to, stress or strain.
  • the sensor 1 15 is not moved into the interior 1 10 of the pipe 105 and the opening simply allows for flow from the pipe 105 to where the sensor 1 15 or other device is located near the opening. When the sensorvalve 120 is closed, the sensor 1 15 is prevented from accessing the interior 1 10 of the pipe 105.

  • Fig. 7 shows that in order to drill or cut a hole in the pipe 810, a drill 700 is introduced into the interior of the housing until the drill 700 contacts the outer surface of the pipe 105.
  • FIG. 8 illustrates a cross sectional view of a drill 700 drilling a bore in an underground pipe 105.
  • the drill 700 is configured to drill or cut a hole in the pipe 105 by applying a downward force and rotating the drill 700 in a clockwise or counter clockwise direction.
  • Other mechanisms can also be used to facilitate drilling or cutting the hole in the pipe 105, such as a clamp 800 to hold the drill 700 in place.
  • a clamp 800 can allow the drill 700 to rest on an uncut pipe 105. Fastening the clamp 800 ensures stability of the drill 700 independent of the force applied.
  • liquid or gas from the interior 1 10 of the pipe 105 can enter the interior of the housing and/or valves 120, 125.
  • the flushing valve 125 can comprise one or more one-way valves to relieve pressure and/or release excess liquid or gas.
  • the debris generated by the drill 700 while drilling or cutting a hole in the pipe 105 is forced out of the pipe 105 due to the pressure in the pipe 105.
  • the drill 700 is removed from the interior 1 10 of the pipe 105 into a retracted positon. In the retracted position, liquid or gas from the interior 1 10 of the pipe 105 can enter the interior of the housing and/or valves 120, 125 and the flushing valve 125 can continue to relieve pressure and/or release excess liquid or gas.
  • the sensor assembly can then be mounted, as shown in Fig. 1 .
  • Saddles shown are illustrated examples only, and can greatly vary in size, configuration, materials, etc. depending on the application and requirements of pipe, liquid or gas pressure in pipe, etc.
