Remote meter readings can be taken at scheduled intervals or on demand. Supplies can be remotely disconnected or reconnected quickly and cost effectively. Built-in fault monitoring and diagnostics provide event and alarm reporting, ensuring maintenance issues can be dealt with quickly. There’s also ...
Engineer was sent next morning re-caped meter and checked everything was ok and advised me things needed doing next as the boiler wasn't new advised to change some of the part plus boiler servicing. Contacted the office to book him a gain for the job. The job is complete now and i ...
Water samples were collected using Niskin bottles at 0 m, 10 m, 20 m, and 50 m below sea surface, and above the seafloor. Temperature, conductivity, dissolved oxygen, and pH, were determined using the multiparameter Meter (IP67, model 8602). These parameters were measured at the two ends...
✓ It has a temperature compensation function and a sensor fault detection function (fault reporting to fire alarm control panel). ✓ Non-polarity, two-bus connection that ensures convenient installation and maintenance. ✓ Designed with an upper cover and a lower cover and installed ...
In a variation of the RF configuration, the transceiver base station may be mounted on a mobile platform, such as a utility company vehicle, to permit rapid, nonobtrusive meter reading, of meters from large numbers of residences over an area limited only by the reliable range of the radio ...
Method and apparatus for automatic remote utility meter reading, utility shut off and hazard warning and correction Apparatus for routine monitoring and automatic reporting of electrical power and gas utility usage also provides means for detecting and reporting to the relevant utility companies, fire de...
