Multivariable Mass Vortex Flow Meter
Sierra Instruments’ InnovaMass 240 In-Line and the InnovaMass 241 In-
sertion vortex flow meters provide a reliable solution for process flow
measurement. From a single entry point in the pipeline, 240 and 241 of-
fer precise measurements of mass or volumetric flow rates.
Multivariable Mass Flow Meters
Mass flow meters utilize three primary sensing elements: a vortex shed-
ding velocity sensor, an RTD temperature sensor, and a solid state pres-
sure sensor to measure the mass flow rate of gases, liquids, and steam.
Meters are available as loop powered devices or with up to three 4-20
mA analog output signals for monitoring your choice of the five process
variables (mass flow, volumetric flow, temperature, pressure and fluid
density). The Energy Monitoring option permits real-time calculation of
energy consumption for a facility or process.
Volumetric Flow Meters
The primary sensing element of a volumetric flow meter is a vortex
shedding velocity sensor. Meters are loop powered. The analog 4-20
mA output signal offers your choice of volumetric or mass flow rate.
Mass flow rate is based on a constant value for fluid density stored in the
instrument’s memory.
Both the mass and volumetric flow meters can be ordered with a local
keypad/display which provides instantaneous flow rate, total, and process
parameters in engineering units. A pulse output signal for remote totali-
zation and MODBUS or HART communications are also available. In-
novaMass digital electronics allows for easy reconfiguration for most
gases, liquids and steam. The Sierra InnovaMass 240 and 241 vortex
meters’ simple installation combines with an easy-to-use interface that
provides quick set up, long term reliability and accurate mass flow meas-
urement over a wide range of flows, pressures and temperatures.
