Sierra was the first to introduce a multivariable mass vortex flow meter to the market in the late 1990s. This technology can measure the mass flow rate of any gas or liquid and are ideally suited for saturated or superheated steam. One instrument and one process connection to measure FIVE process parameters to simultaneously measure mass flow rate, temperature, pressure, volumetric flow rate, and fluid density.
InnovaMass 240 VTP
Inline mass flow measurement with direct reading of FIVE process parameters at the same time; accuracy is ± 1.0% of rate for liquids and 1.5% of rate for gases and steam over a 30:1 range
Inline volumetric vortex flow meter for liquids, steam or constant density gases; Product accuracy is ± 1% of rate for liquids and 0.7% of rate for gases and steam over a 30:1 range
InnovaMass 241 VTP
Insertion style vortex mass flow measurement in process pipe sizes up to 72" (2m) with accuracy of ± 2.0% of rate over a 30:1 range; Ideal for high pressure distribution up to 5000 psig (345 barg)
Insertion style volumetric vortex flow meter for liquids, steam or constant density gases; For pipes 2-inches (5cm) up to 72-inches (2m); Accuracy is ± 1.2% of rate for liquids and 1.5% of rate for gases and steam over a 30:1 range
