Liquid Density Meters

ISSYS has developed a family of liquid density meters.

FuelSenseTM LD and MassSenseTM LD

ISSYS has developed a small, unique fuel density meter, FuelSenseTM LD, that can satisfy the requirements for the petrochemical and emerging alternative energy fuel market at an affordable price. Customer safety in harsh environments has been the driving force of many of the features of the meter.

The density meter is often used in a by-pass configuration with large diameter processing pipes. This density meter can interface with an external temperature probe to measure the process fluid temperature in the center of the large diameter pipe more accurately.

Remote Data Logging – The meter has an option that enables 2GB of data to be logged and stored internally. A laptop can then be used to extract the data. Six months of density data could be pulled out of a remote meter with this option.

External Temperature & Pressure Sensor – to get best temperature accuracy with respect to the process fluid going through the main line being sampled, an external temperature probe option is available (see photo to the right). An external pressure sensor option is also available if needed.

For applications where the fluid is not flammable the MassSenseTM LD version of the density meter can be used. Meters without the LCD and push buttons are also available.

The FuelSense and MassSense products are CE marked. Download the CE Declaration of Conformity.

Flights leaving Israel stopped due to fuel contamination
05/05/2011 14:50
Planes cannot fill tanks or leave Ben Gurion Airport; some incoming flights stop in Greece or Cyprus instead. Israel halted most departures from Tel Aviv's Ben-Gurion international airport on Thursday after routine checks found aviation fuel supplies were contaminated, an airport spokesman said. The gas problem was discovered a week and a half ago, but actions were not taken until Thursday. Only aircraft that flew in with sufficient fuel to reach their next destination were being allowed to depart as scheduled.
Donít let this happen to you! - FuelSense meter can be used to detect contaminated fuel.

Embedded Density Sensor

A smaller density sensor, based on the FC-10 fuel cell concentration sensor design is available. It can be used for nonflammable liquids, ideal for OEM applications where small size is critical. Cable or connector options are available.
