1.3 Required differential pressure
Density transducers of the DIMF series measure independently of flow rate and also at flow rate zero.
Their application is therefore normally problem-free. Care must, however, be taken to ensure that the
operating flow rate in the transducer
- updates the sample fast enough
- equalizes the temperature in the tranducer
- avoids air or gas bubbles or
deposits in the oscillating tube
- does not cause cavitation in the oscillating tube
- does not cause wear through abrasives
Recommended operating flow rate through the density transducer:
