Rising energy costs have made improving compressor efficiency a high-profile challenge for many plant managers. Leaks are frequently a significant source of lost energy, sometimes wasting up to 30% of compressor output. Compressed air system leaks can also cause a drop in system pressure, force equipment to cycle more frequently and lead to additional maintenance requirements and downtime.
Clearly, optimizing compressor system efficiency and identifying and repairing leaks is critical to reducing plant operating and maintenance costs. Monitoring compressed air in multiple lines can also help plant operators optimize facility loading, effectively schedule maintenance operations and allocate energy costs.
Thermal flowmeters have demonstrated their ability to facilitate compressor audits and enhance plant management and control strategies. Virtually immune to variations in temperature and pressure, the thermal flowmeter provides an accurate mass flow measurement under varying loads. Its rugged, no-moving parts design is also ideal for the high-vibration environment found in most compressor applications.
A variety of sophisticated self-diagnostics and field-adjustment features built into the flowmeter help ensure traceability in compressor audits. The instrument also offers outstanding low-flow sensitivity, fast response, and low maintenance requirements for point-of-use measurement, cost-allocation and system diagnostics applications.
Designed for easy insertion into compressed air lines, insertion-type thermal flowmeters include compression fittings and hot tap mounting to facilitate removal of the sensing probe for portable applications, or for service and maintenance procedures.
Fox Thermal Instruments offers FM and CSA approved air flowmeters for operation in hazardous areas, available with a variety of input-power, output-signal, process-connection and packaging options.
