Read five process variables with a single installed device!

Our Model 240 Innova-Mass provides a direct reading of mass flow rate from a single entry point in the process line and provides analog and digital outputs of five process variables: mass flow rate, volumetric flow rate, temperature, pressure, and fluid density. The ability to sense all process conditions in a single location greatly improves measurement accuracy and eliminates the costly requirement for additional line penetrations associated with traditional mass flow measurement systems.

The sophisticated on-board flow computer also incorporates AGA-8 algorithms for natural gas measurement to reduce billing and contract disputes. Smart electronics provide access to all measured variables and programming menus, and permit field-configuration directly from the control panel or workstation via RS485, MODBUS or HART protocols.

Product accuracy is ± 1% of rate for liquids and 1.5% of rate for gases and steam over a 30:1 range. The Model 240 is hazardous area approved by FM, CSA, and CE.

Von Karman demonstrated that, when a fluid flows past a bluff body, an alternating series of vortices is shed from each side, creating areas of fluctuating pressure. The frequency of the vortices is directly proportional to fluid velocity. In commercial vortex flow meters, the bluff body is called a "shedder bar". The common trait of all shedder bars is sharp corners, which enhance the energy of the vortices and ensures boundary-layer separation at two defined points.

This characteristic is responsible for the extraordinary linearity of the frequency of vortex shedding over a wide velocity range. Innova-Mass uses a piezoelectric sensor to measure the frequency of the Von Karman vortices. This results in an intrinsically linear measurement of fluid velocity over a wide range of Reynolds numbers. The meter’s smart electronics automatically calculates the Reynolds number based on the actual measured density and viscosity, and then corrects for any non-linearity at lower Reynolds numbers.

Innova-Mass incorporates temperature and pressure sensing to calculate fluid density at a single point. The solid-state micro-machined silicon pressure transducer and platinum resistance temperature detector provide exceptional accuracy and stability. Accurate, reliable and cost-effective mass flow measurement Conventional vortex flow metering systems utilize inputs from external temperature and pressure transmitters to supply an inferred mass flow rate output. In these inferential mass flow devices, temperature and pressure sensors are located somewhere in the pipeline either upstream or downstream of the vortex flow meter, but typically not at the same location in the pipeline.

This causes errors in calculating fluid density, resulting in mass flow accuracy in the ± 3 to 5% range. Because Innova Mass measures all process variables in a single location, it offers mass flow accuracy in the ±1 to 2% range, and significantly reduces the complexity and cost of installation.
