Series Scirocco 1000
Thermal Mass Flow Meters (Series Scirocco 1000) are precision instruments used as vital measurement tools in various industrial processes. The direct measurement of mass flow completely eliminates the need for separate temperature and pressure compensation, making them suitable for high-efficiency pipeline systems where accuracy, reliability, and long service life are absolutely critical.
Operating on King's Law, our instrument contains two Platinum RTD temperature sensors. One sensor measures the current fluid temperature as a reference, while the second is precisely heated. When flow begins, heat is drawn away via forced convection, and the amount of heat lost directly correlates to the mass velocity of the fluid. This advanced thermodynamic technique achieves an exceptional 100:1 turndown ratio.
Working Principle
The Thermal Mass Flow Meter, Series Scirocco 1000 is a precision instrument that measures gas & air mass flow and is used in various industrial processes.
Its measuring principle is based on the fact that whenever a fluid of a certain temperature is passed over any substance hotter than the fluid, the heat of the hot substance is taken away because of forced convection by the fluid, and the temperature of that substance drops. This fall in temperature is related to the mass flow of the fluid passing over the substance. If one can measure the amount of heat taken away by the flowing fluid one can calculate the mass flow rate.
A Thermal Dispersion Mass Flowmeter contains two Platinum RTD temperature sensors for this purpose. One sensor measures the current fluid temperature as a reference. The second sensor is heated and has a constant temperature differential relative to the first sensor. When the flow of air/gas starts heat is taken away from the warmer sensor. The amount of heat taken away is having a direct relation with the mass velocity of the fluid. This eliminates the need for temperature and pressure compensation.
Heated sensor maintains a constant temperature above the fluid.
Flowing fluid carries heat away from the heated sensor.
Temperature of the heated sensor decreases.
Temperature difference is proportional to the mass flow rate.

| Parameter | Vortex Flow Meter | Superior Tech Thermal Mass Flow Meter |
|---|---|---|
| Method of measurement | Measures volumetric flow that needs to be converted to mass flow, using calculations. | Directly measures mass flow. Hence more reliable. |
| Pressure and Temperature Compensation | Required, as it is basically a volumetric flow meter hence signal generated is proportional to Velocity. | Not Required as the signal generated is proportional to the Mass velocity of Fluid. |
| Existing pipeline modifications for Installation | Design is based on velocity and not online size. As a result, the customer's line size and flow meter size may differ. | No Modification is essential in most the cases. |
| Installation | Easy, but pipeline size matters. | Very Easy. |
| Recalibration | This has to be done on Flow Rig. | Has to be done on Flow Rig. Relatively less expensive, as Manas offers this service at an affordable cost. |
| Suitability for low velocity | Not Suitable as vortices are not generated below 6 m/sec velocity. | Works even at velocity as low as 1 m/sec. |
| Turndown Ratio | (10: 1) | Much better (50: 1) |
| Compensation | Compensation depends on temperature. Chances of error are because of the high thermal resistance of the temperature sensor. | Compensation not required at all. Hence more reliable. |
| Error elements | There are three sensor elements - Temperature, Pressure and Flow sensor. Thus, there are three sources of error. | There is only one sensor element - Flow sensor. Hence it is more reliable. |
