Valve-Tronic Plus™ Flow Controller

The Flowlink Flow-Connect is an easy to use flow controller. It can be used to control almost any pump-flowmeter combination. Besides pump control it also has the ability to register additional sensor signals, like pressure of temperature. The standard Flow-Connect is suitable for connecting 1 pump, 1 flowmeter and 1 additional sensor. More complex flow-control is available on request. The Flow-Connect has 4 standard flow control functions. Pump Controller – 0 – 100% pump Flow Controller – flowmeter controlled flow Batch Controller – batch dosing Additional Sensor Controller – eq. pressure or temperature control The Flow-Connect can accept different control signals, like 0-10Volt, 4-20mA, Pulse and Modbus.

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).

Electrodynamic flow sensor for the measurement of low flow rates from 0 to 100 kg/h. For pipe diameters up to 1 m. Ideally used in leanphase conveying. In free fall conditions with at least 2 m/s drop speed. • suitable for very low concentrations • ceramic coating prevents sensor wear

MULTI-ZONE TEMPERATURE CONTROL- AND MONITORING SYSTEM WITH NON-CONTACT FLOW MEASUREMENT. Due to the design, dimensioning and selection of the used components, enersave temperature control systems are the most efficient systems on the market with the highest flow rates at operating point. By using the frequency inverter, the already high basic efficiency is optimized and the pump characteristic curve will be optimally adapted to the respective operating conditions. The flow measurement of the individual temperature zones is carried out using noncontact measurement technology according to the ultrasonic principle.
