1 15 Flow Meter SCQ Measurement principle: spring/piston system Flow measurement with direction indication Response time < 2 ms Compact design Withstands pressures up to 420 bar Wide range of viscosity p/t/q measurement possible with connection block Flow measurement with direction indication for mobile and stationary measurement jobs Function When there is a flow from to or to, the piston (K) is moved. When at rest, the spring (F) and piston (K) are in equilibrium. The stroke change (S) is proportional to the flow volume and is converted by the built-in electronics to a measured value. y the change in direction of the piston ( to ) flow directions can be shown (e.g l/min.). The response time of the piston movement is less than s. SCQ measurement principle pplication In the field of high pressure hydraulics, the rapid capture of the amount of flow is of great significance. The reaction times of the SCQ s enable the dynamic behaviour of hydraulic systems to be measured. The indication of direction is helpful when searching for faults in hydraulic systems. Rapid load changes, which can cause damage for example in valves and pumps, can be determined. Installation with a connection block permits the combined measurement of p, T and Q. Rapid assembly of the SCQ s is achieved with an in-line adapter for tube or hose installation. Robust design makes possible extreme condition applications, such as, for example, high load changes or rates of pressure increase. 64
