Monitoring Generator Sets in Standby Mode Increases Reliability

Remote Monitoring of Electric Generator in Standy Mode
Electrtic generators used as backup power sources play a critical role in maintaining operations at many facilities. They may be automatically test run periodically, but still sit idle for extended times. Continuous remote monitoring of equipment condition can reduce the risk of a failed start.

Acromag, a globally recognized manufacturer of signal conditioning equipment, has authored an application note outlining the extent of remote monitoring that should be employed and how to accomplish it.

The application note is included below. Share your process signal conditioning and transmitting challenges with product specialists, combining your process knowledge with their product application expertise to develop effective solutions.

Thermal Instrument Company
Thermal dispersion mass flow meters provide an accurate means of mass flow measurement with no moving parts and little or no encroachment on the media flow path. There are a number of different configurations to be found among various manufacturers, but all function in basically the same manner.

Two sensors are exposed to the heat transferring effect of the flowing media. When the media composition is known, the mass flow can be calculated using the meter reading and the pipe cross sectional area. One of the flow meter sensors is heated, the other is allowed to follow the media temperature as a reference. The heat dispersion from the heated sensor is measured and used to calculate mass flow.

Some positive attributes of thermal dispersion flow meters:

  • In-line and insertion configurations available to accommodate very small to large pipe sizes
  • Rugged Construction – Stainless Steel with available protective coatings and other specialty metals
  • No moving parts
  • Measure liquid or gas in general, sanitary, and ultra pure applications
  • Measurement not adversely impacted by changes in pressure or temperature
  • Wide range of process connections 
  • In-line versions provide unobstructed flow path
  • Wide turndown suitable for extended flow range
  • Back up sensors for extended life
  • Sensors do not contact process media
  • Flow and total flow measured
  • 4-20 mA output interfaces easily with other instruments and equipment

Foot Valves: Basic, Hidden, Essential

Colton Industries
A foot valve is a purpose specific check valve. Designed for immersion in a well, tank, or other liquid containing vessel, it serves as a one-way inlet valve on piping leading to the suction side of a pump. Foot valves and their connected piping will extend downward from the pump suction elevation. The purpose of the valve is to maintain prime on the pump by preventing the water column in the suction line from collapsing, due to gravity, and draining all the liquid from the suction side of the pump system.

For industrial applications, there are numerous versions of foot valves available in varying sizes, capacities and materials of construction. The function of the valve is simple, so the key selection criteria can be focused on features that will contribute to longevity and reduce or eliminate any maintenance burden.

The data sheet below provides some good illustrations of a foot valve and how it is installed. Share your fluid processing and control challenges with application experts, combining your process and facility knowledge with their product application expertise to develop effective solutions.
