With a footprint the size of a handheld organizer, you can fit this meter into any tight space for your low-flow only is the footprint small so are the flow rates. With a range of to lb/hr ( to 27 kg/h), you can measure mass or volume flow for drops of liquid or other Micro Motion meters, the LF-Series offers all the benefits of Coriolis.

3 High accuracy, for a quicker ROI No moving parts, for reduced maintenance costs and downtime Direct measurement of mass, volume, temperature, and density for reduced instrumentation requirements Measurements unaffected by changing fluid properties, for no special installation requirements or manual calculationsApplicationsMicro Motion LF-Series meters are ideal for many low-flow applications, including flavoring, fragrances, and catalysts. LF-Series meters are designed to meet the demanding low-flow needs of a wide variety of industries such as chemical, petrochemical, life sciences, food and beverage, and oil and transmitters with MVD LF-Series transmitters are specially designed to work with LF-Series sensors on your low-flow applications.

4 LF-Series transmitters incorporate MVD technology an innovative, multivariable, digital signal processing capability. MVD technology: Improves ease of use with an easy-to-use display Reduces downtime with enhanced diagnostics Lowers your flowmetering costs with a 4-wire features include: Milliampere and frequency/pulse outputs Transmitter and process control functions in a single device Field-mount or DIN rail mount transmitter Optional NEMA enclosures (field-mount transmitters only) Optional filling and dosing application softwareMake your process more profitableMicro Motion LF-Series sensors and transmitters can be installed as part of a HART Bell 202 multidrop network, a Modbus RS-485 digital communications network, or a FOUNDATION fieldbus system.

5 All transmitters support Emerson Process Management's PlantWeb field-based architecture, which uses the power of intelligent, interoperable field devices to improve plant Motion is known worldwide for increasing plant efficiency, production, and profitability. More than 500,000 Micro Motion meters are installed and working in processes just like yours.
