ATSENSE Fuel Flow and Density Detector FDS Series
The detector is an all-in-one device that includes sensors for flow, density, temperature, and pressure, alongside a filter. It simplifies measuring fuel flow rates, delivering accurate, simultaneous readings like instantaneous flow, mass conversion, and total flow. Its integration with the FDM series flow and density meter further expands its measurement capabilities, making it ideal for detailed fuel analysis. Manufactured by ATSENSE INC., Tokyo.Wide-range measurement The FDS-1213 has a wide-range capability of 0.06 to 108L/h, and the FDS-1214 a wide-range capability of 0.3 to 600L/h. Low pressure loss The fuel flow and density detector integrally combines a 10μm filter and a sensor. Since both the filter and sensor have low pressure loss, measurements can be made without inserting a pressure device in the fuel line. Responding to increasing fuel diversification All of gasoline, light oil, and alcohol can be measured.
