Badger Meter Europa Coriolis mass flow meters
2 Coriolis mass meters Coriolis mass meters are recommended for the direct, continuous measurement of the mass of flowing liquids independently of their conductivity, density, temperature, pressure and viscosity in the food, chemical and petrochemical industries. They are best suited to measure chemicals, liquid food, suspensions, molasses, inks, lacquers, pastes, etc. Measuring principle Coriolis mass flow metering is based on the physical principle that a force, the so-called Coriolis force, acts on a mass that is moving towards or away from the point of rotation within a rotating system. The symmetrical arranged measuring tubes 1 and 2 are vibrated against each other in the X and Y axis. The limbs RS 1 and RS 2 of the measuring tube 1 and the limbs RS 1 and RS 2 of the measuring tube 2 oscillate on a circular segment in case of zero flow.

3 Coriolis RCT1000 mass flow meters Hazardous location transmitter The Badger Meter RCT1000 Coriolis mass flow meter identifies flow rate by directly measuring fluid mass over a wide range of temperatures with a high degree of accuracy. For fluids consisting of two liquids or a liquid with suspended solids, the RCT1000 Coriolis system can derive the concentration and mass Specifications of each fluid based on the density measurement. Furthermore, the unobstructed, open flow design makes it suitable for a variety of fluids such as slurries and other viscous, nonconductive fluids that are difficult to measure with other technologies. Simultaneous measurement of: Mass flow Density Temperature Pipe size 1.6 76.2 mm (1/16 3 ) Accuracy Zero stability Repeatability Liquids: up to± 0.1% of flow rate up to± 0.025% of full scale up to± 0.05% of flow rate Process temperature range -40 200 C (-40 392 F) Wetted material Application 316L stainless steel General area or hazardous location Density: up to± 0.0005 g/cm 3 Advantages: Unobstructed open flow design Low-maintenance operation with no free-moving parts ModBus RTU, ModBus TCP/ IP, HART, EtherNet I/P network options Advanced fluid diagnostic tools Batching and PID control Advanced software
4 Applications Unlike many flow measurement technologies, Coriolis mass flow meters can directly and accurately measure the mass flow of fluids over a wide range of fluid temperatures and viscosities. The Coriolis design and measurement principle allows the meter to be an exceptional device in measuring: Vegetable oils and fats Homogeneous suspensions and slurries Adhesive, glue or binding materials Coatings and hardeners Dyes, fragrances, vitamins and other additives Oil and fuels Chemical Pet food Textiles Combustion control Asphalt Engine test stands
5 Operating principle Coriolis flow meters simultaneously measure mass flow rate, density and temperature. As fluid flows through the vibrating sensor tube, forces induced by the flow cause the tube to twist slightly. These small deflections are measured by carefully placed sensors. A phase shift occurs between sensor signals that is directly proportional to mass flow rate. As the fluid density varies, the resonant frequency at which the tube vibrates changes which is also measured by the sensors. Temperature is measured by an internal RTD in order to calculate thermal effects on the tube vibrating frequency. Types of measurement Mass flow rate Density Temperature Derived from the phase shift between inlet and outlet sensing coils Derived from vibration frequency Measured and used to correct for changes in the stiffness of the vibrating tubes Internal operation (U-Tube design) Inlet Outlet Sensing coils U-Tubes Drive coil Phase shift NO FLOW Bottom view FLOW Bottom view Δ T = 0 Δ T > 0 Density frequency HIGH DENSITY LOW DENSITY RCT1000 Coriolis mass flow meters operate at low frequencies which reduce the formation of air slugs in liquids with entrained air. This operation keeps liquids more homogeneous and provides less erratic readings.
6 Controls & system integration RCT1000 transmitters provide a variety of ways to integrate the meter output into new and existing operations. The batch and PID functionality enables direct control of devices, such as valves, by use of digital or analog outputs. Digital outputs can also be programmed to indicate low and high alarm conditions. Network options EtherNet/IP ModBus TCP/IP ModBus RTU HART Signal outputs Frequency Pulse PWM 4 20 ma (qty 3) Quick configuration Easy-to-read LCD screen Remote or integral mounting PID loop control example Slurries are used in many products, but the proper mix needs to be controlled. As a slurry is pumped through the Badger Meter Coriolis flow meter, the meter measures the percentage of concentrate. Based on this measurement, the PID controller output from the RCT1000 transmitter will modulate the water addition to the mixer to ensure the exact concentration is achieved. In conjunction to the PID control function, the RCT1000 transmitter can also supply analog output or network connectivity for continuous monitoring of the percentage of solids as well as flow rate information to the control room.
