Thermo Scientific’s Sarasota line of gas density instruments provide a measurement that can, with the use of auxiliary flow computers or other electronics from the company or third party vendors, provide additional data for specific gravity, calorific value, or molecular weight. Three basic meter styles provide for direct insertion, bypass, or pocket mounting arrangements. Two versions of each type are offered, with the first providing a frequency output and 4-wire PT 100 temperature sensor output for use by a flow converter or other computational device. The second version has an onboard HART compliant density converter with 4-20 mA output.
As the measured gas flows through the meter, it interferes with the base frequency of the vibrating sensor tube in proportion to the density of the gas. The instrument measures the change in vibration frequency, which is used to calculate the density. The onboard precision RTD provides for temperature compensation. Other features include:
- Readings unaffected by pressure
- Available for use in hazardous environments
- Third party certifications
- Connection options
- Wide temperature range operation
- Interfaces with Thermo Fisher flow computers, or other brands
- Continuous online density monitoring
Variants of the instrument accommodate a wide range of application and installation requirements. More detail is provided in the datasheet included below.
