Mass Probe Flowmeter has ±.50% FS accuracy.
September 10, 2002 - Model 62-9 with integral 9500 microprocessor electronics performs mass flow measurement of liquids and gases via its unobstructed flow tube with non-wetted sensors. Providing integral local control and display in explosion proof housing, flowmeter allows for remote mounting of electronics to distances up to 4000 ft. Flow signal linearity and temperature effects are corrected by microprocessor using operating parameter data stored in its 64K EEPROM memory.

Model 62-9/62T-9/9500 Integral Thermal Mass Probe Flowmeter
The Thermal Instrument Model 62-9 Mass Probe Flowmeter With Integral 9500 Microprocessor Electronics brings an element of versatility to Mass Flow Measurement of Liquids and Gases.
A uniquely designed microprocessor controlled electronics provides integral local control and display in an explosion proof housing. Optional Remote Mounting of the electronics to a distance of 4000 ft provides additional versatility depending on the application.
Flow signal linearity and temperature effects, determined at calibration, are corrected by the microprocessor using operating parameter data stored in EEPROM memory.
DESIGN FEATURES
> Unobstructed Flow Tube with Non-wetted Sensors mounted on the Inner Surface of the flow tube of the Insertion Probe Design permits measurement of Gases, Liquids and Slurries.
> Wide Selection of Probe Materials: 316 SS is standard. Corrosion resistant materials such as Hastelloy C, Monel, Inconel, Carpenter 20 as well as carbide and fluorocarbon coatings are available.
> Hi Temperature designs to 1000 F.
>Wide Flow Range on Gases is greater than 100:1
> Vent Flow Measurement at near atmospheric conditions and low flow.
> Rate and Totalizer Ultra-bright LED display
> NIST Traceable Calibration on user gases and liquids. Calibration in user piping configurations
> Isolated Fluid Temperature Signal, 4-20MA from an RTD Sensor on the Flow Tube.
> Multi sensor Design for large ducts and stacks
> Electronics suitable for Remote Mount to 4000 ft.
> Totalizer Data is stored in the EEPROM memory on power loss and restored on startup. No batteries required.
