1. A monitoring device for a pipe system, the monitoring device comprising:a housing defining a mounting surface and a pair of mounting receptacles on a mounting side, the housing configured to mount on an exterior surface of a pipe element of the pipe system, the housing comprising
a cover, and
at least one cover fastener securing the cover to the body;
a tamper-resistant housing fastener configured to resist unfastening without a special removal tool; and
a strap assembly, the housing fastener received within a first mounting receptacle of the pair of mounting receptacles to secure the strap assembly to the housing, the strap assembly comprising a first strap and a second strap,
the first strap comprising a first mounting end, a first adjusting end distally located from the first mounting end, and an intermediate portion therebetween, the first strap comprising a first mounting tab proximate to the first mounting end, the first strap further comprising an insert tab proximate to the first adjusting end, the housing fastener connecting the first mounting tab within the first mounting receptacle;
the second strap comprising a second mounting end, a second adjusting end distally located from the second mounting end, and a second intermediate portion therebetween, the second strap comprising a second mounting tab proximate to the second mounting end, the second mounting tab coupled to a second mounting receptacle of the pair of mounting receptacles, the second strap defining a plurality of adjustment slots proximate to the second adjusting end, each adjustment slot aligned in an axial direction of the strap assembly and sized to lockably receive a portion of the insert tab in any one of a plurality of insert positions, each insert position corresponding to a different inner diameter of the strap assembly when the housing fastener is tightened, a portion of the first strap proximate to the first adjusting end crossing a portion of the second strap proximate to the second adjusting end and a portion of the first strap positioned radially inside the second adjusting end of the second strap, the insert tab lockably coupled to the second strap when the housing fastener is tightened,
wherein the cover fastener is configured to prevent disassembly of the cover from the body without first removing the housing fastener.
