When a Washington state wireless carrier needed reliable level measurement of their tower backup diesel generators, they turned to Flowline. Select towers are mission critical and they are integrated with gensets for continuous service. The gensets auto-run once a month to verify their operational status and the diesel tank level is then transmitted over the network to the fuel supplier. The system integrator said that the prior hinged mechanical float level sensors were susceptible to locking up when the temperature dipped below freezing, and this had caused reporting errors. For this reason, Flowline suggested our solid-state guided wave sensors that are ideal for diesel and are unaffected by temperature variations. The guided wave sensor provides reliable level data to the tower SCADA which uploads the data for fuel replenishment. Flowline is reliable level measurement.
