FloScan Fuel Log for Diesel Generators

FloScan has been designing and manufacturing fuel computers for use on diesel generators for 3 decades, but with the expansion of federal, state and even municipal regulations on the operation of industrial and construction generators their presence in that marketplace has expanded exponentially. While there are other systems that claim applicability, only FloScan fuel sensors were designed specifically for use on diesel engines. Their accuracy meets all regulatory reporting requirements; their reliability is legendary. The unique fail-safe design of the FloScan fuel flow sensor guarantees it cannot cause an engine failure, a claim that other types of flow sensors simply can’t make. That is why FloScan sensors are certified by the FAA for use on general aviation aircraft and why FloScan dominates the marine market with a long list of applications on military and government vessels.

FloScan Fuel Computers are the gold standard for use on land-based diesel generators of all types.

"During the process of reviewing the bids, Dan Formantini, the person responsible for the operational integrity of all the generators on the base, began comparing the various types of flow sensors and monitoring systems," said Donatini. "He did his own research on system performance and reliability and came to the conclusion that the only fuel computers he wanted on the NAS Fallon generators were the systems manufactured by FloScan."

FloScan systems for generators start with the unmatched reliability of its diesel fuel sensors, which provide the accurate fuel consumption data. It is routed to the FloScan Fuel Log gauge, the latest addition to FloScan's full line of digital instruments for diesel engines rated from 30 - 5000 kW. Fuel Log addresses the need for accurate flow measurement to determine baselines for NOx emission reporting, but it can also point out poor engine performance (malfunctioning injectors or injection systems; faltering turbochargers, or other performance problems) as well as identifying incidents of fuel theft through discrepancies

between tank fill-up records and the totalizer reading. Fuel Log can also be used for fuel billing purposes when generators are being used on a “per hour or per job” basis by monitoring precise fuel consumption.

FloScan Fuel Log systems provide Instantaneous net fuel burn rate; Cumulative (non-resettable) fuel totalizer; Resettable fuel (job) totalizer; Resettable engine (job) hour meter; Pulse signal output for instantaneous net fuel usage and it can be interfaced with FloScan DataLog or user specified data acquisition software for recording fuel usage. The system offers (+/-) 2% accuracy with retro-calibration on generator applications with models available to read in U.S. gallons or liters. The system operates on 12VDC and a 32V/24V voltage reducer is available to meet any installation requirements.

The Installation Process

With any government project installation is an important part of the contractor’s responsibility. JHME’s experience installing FloScan marine systems provided all the background necessary for installing FloScan generator systems at Fallon.

“Being new to dealing with industrial and construction generators we were pleasantly surprised at how simple the FloScan generator systems were to install on land-based generators,” Donatini told us in a recent interview. “Marine installations are more challenging for any number of reasons, not the least of which is we usually find ourselves working in cramped engine rooms around a vessel’s main propulsion engines and generators, which can be crammed into very tight spots. That can limit the places we can locate the fuel sensors. Fortunately, that was not the case at Fallon. The generators housed inside large buildings or in the smaller outbuildings offered excellent accessibility for planning out the installation process. We were able to construct simple tree-like assemblies for the inlet and return line flow sensors and in a number of cases the Fuel Log gauge was mounted on a small panel right on the tree. The construction-type generators enclosed in tight metal housings were a little more challenging, but really didn’t present any significant installation problems.”
