KS100FC Coriolis Mass Flow Controller
Summary:
Coriolis mass flow controllers are highly regarded for their measurement accuracy and insensitivity to fluid properties. The KS100 features a uniquely shaped single-loop sensor that forms part of an oscillating system. As the fluid flows through the sensor loop, Coriolis forces induce a variable phase shift, which is detected by the sensor and transmitted to a DSP processor on the integrated circuit board for computation. The resulting output signal, directly proportional to the actual mass flow rate, delivers unparalleled high performance even under varying process conditions such as pressure, temperature, density, conductivity, and viscosity. The KS100 simultaneously measures mass flow, fluid density, and temperature, and outputs all three parameters. The KS100 series of mass flow meters offers two accuracy classes: ±0.25% for liquid measurements and ±0.5% for gas measurements. This level of accuracy is sufficient to meet the needs of most customers, making the instrument suitable for both laboratory testing and demanding industrial applications. To accommodate challenging industrial environments, certain models are certified to IP67 for dust and water resistance and to IICT4 for intrinsically safe explosion protection. In addition to standard analog input/output interfaces, the KS100 also supports RS-485 and RS-232 communication, using the standard Modbus RTU protocol.
