Unique multivariable design
The Panametrics, a Baker Hughes Company, PanaFlow MV84 In-line Multivariable Mass Vortex flow meter is
the next generation vortex meter. PanaFlow MV84’s multivariable design consists of a vortex shedding
velocity sensor, an RTD temperature sensor and a solid state pressure transducer that measures the mass flow rate of steam, gases and liquids. Other meter types use external process measurements to calculate mass flow. The temperature and pressure devices are typically not installed in the same location as the flowmeter. Process conditions can vary greatly between the two locations, causing inaccurate mass flow readings. PanaFlow MV84 measures velocity, temperature and pressure at the same location, which provides more accurate process measurement. Portfolio of flow meter solutions Panametrics is committed to providing customers with the best technologies for their flow measurement needs. PanaFlow MV84 is the newest addition to the PanaFlow family of flow meters, providing effective solutions for smaller pipe sizes for a variety of applications. Panametrics offers the PanaFlow MV84 in a number of configurations to best suit your application measurement needs.

Field service solutions
Panametrics has a global field service team ready to assist in the start-up and commissioning of the PanaFlow MV84 flow meters. This service includes validating the proper installation and programming of the meter, and can include customized training for theory, operation and maintenance. Regularly scheduled preventative maintenance visits will provide peace of mind, ensuring that the meters work to specification and your expectation for years. Mass flow measurement—true multivariable The MV84 offers flow computer functionality in a compact field device. The VTP option incorporates temperature and pressure sensors to provide an instantaneous reading of compensated mass flow rate of gases, liquids and steam. In addition to outputs for totalized mass and alarm settings, the field configurable electronics deliver up to three analog
4-20 mA outputs of five process measurements, including volumetric flow rate, mass flow rate, pressure, temperature and density. Alternate configurations for mass flow include a temperature only compensation (VT), best used when in saturated steam applications, and an integrated RTD with an external pressure transmitter (VT-EP) when a full function pressure transmitter is desired.

Energy measurement in liquids and steam
The VT-EM energy monitoring option enables real time-of-flight diffraction calculation of energy consumption for a facility or process. The meter can be programmed to measure steam, hot water or chilled water. This option uses the MV84 flow meter to monitor one side of the process, either sent or return, and uses the input from a second separate temperature sensor on the opposite leg of the process to calculate the change in energy. Selectable energy units include BTU, joules, calories, Watt-hours, Megawatt-hours and Horsepower-hours. The local or remote electronics indicate two temperatures, delta T, mass total and energy total. For energy measurement in steam, the VTP-EM option adds a pressure transmitter to offer better accuracy.

Volumetric flow for most gases and liquids
The base model MV84 delivers a direct reading of volumetric flow rate—generally the most cost-effective solution for liquid flow monitoring—in applications ranging from general water flows to hydrocarbon fuel flow measurement.
