A metering system (100) that may find use to generate values for measured parameters of materials (104). The metering system (100) may be configured with a metrology device (112, 114) configured to generate a first signal (116) in digital format to convey information about material (104) in a conduit (102). The metering system (100) may also include an accessory (126) coupled with the metrology device (112, 114), the accessory (126) configured to use the information of the first signal (116) to generate a second signal (128), the second signal (128) conveying information that defines a measured parameter for the material (104). In one implementation, the accessory (126) comprises executable instructions that configure the accessory (126) to exchange information with the metrology device (112, 114) so as to verify a regulatory status for the metrology device (112, 114).
A safety device (122) that is useful to release load on a spring (136) found in an actuator (100). In one embodiment, the actuator (100) can have a housing (104) comprising a pair of housing members (106, 108) and a fastening device (112) coupling the pair of housing members (108, 110) to one another. The embodiment can also have an output shaft (118) extending longitudinally through the housing (104), the output shaft (118) having an end configured to couple with a process device (102). The embodiment may also have a spring (136) coupled with the output shaft (118). The embodiment may further have a safety device (122) coupled to the spring (136) and configured to operate to reduce loading of the spring (136) from a first load to a second load. In one example, the safety device (122) is in position to prevent access to the fastening device (112) at the first load and to allow access to the fastening device (112) at the second load so that the pair of housing members (108, 110) can separate to allow access to the spring in the housing.
An energy harvester for use in-line with a pipe to harness potential and kinetic energy of fluids flowing therein. Structure for the energy harvester may include a shaft and a blade extending radially therefrom. The shaft can penetrate a housing that operates as a pipe section to install the device in-line with pipe. The shaft can couple with an electrical generator. A load may connect with voltage terminals on the generator so that fluid impinging on the blades will rotate the generator to power the load, effectively harvesting power from the flowing fluid. In one implementation, a load control device that couples with the generator voltage terminals controls a pressure characteristic of the fluid, such as pressure drop, by applying an electrical load on the generator and controllably impeding rotation of the shaft.

A test apparatus (100) to test operation of a gas meter (108). The test apparatus (100) may include metrology devices, namely, a master meter (110) and a measuring device (112), typically with a sensor to measure ambient conditions that prevail at the master meter (110) and the gas meter (108). Each of the metrology devices (110, 112) can be configured as a self-contained, independent unit that can process analog signals to generate a digital signal (114). A controller (128) may process these digital signals (114) to convey information that defines flow volume for gas (122) that flows through the gas meter (108). The controller (128) may also be configured to verify a regulatory status for the metrology devices (110, 112). These configurations can use validation data stored on the metrology devices (110, 112) separate and independent of the controller (128). In this way, the test apparatus (100) assumes a modular structure that allows the metrology devices (110, 112) to swap into and out of the test apparatus (100).
