Digiflow Systems products DFS-2 Turbine Flow Meter and DFS-2W Disposable Turbine Flow Meter are NO LONGER  AVAILABLE.

Alternative products include the Equflow PVDF and PFA Flow Meters and
the Equflow Disposable Flowmeter Clamp Holder System available from Clark Solutions.

If you currently use Digiflow System’s products in your application or designs
please contact the Clark Solution’s sales engineering team at 800-253-2497 regarding your application and possible alternative products.


The Equflow PFA Turbine Flow Sensor has low flow sensing capabilities in a wide range of applications, and is suitable for clear, opaque, neutral, corrosive and aggressive liquids including fuel.

An ultra-lightweight turbine follows the fluctuation of flow very accurately and generates a high resolution IR reflected digital output signal.

Aggressive media can be measured, as the only wetted materials are PFA and a ruby bearing.

K-factors (pulses per liter) are factory determined and provided for each flow tube. Customer specified K-factors can be accommodated and are programmed at the factory.

External optional electronic packages for the PFA Turbine Flow Sensor include model PD6300 Flow rate indicator and totalizer and PD6310 batch controllers. Rich in features, these products provide complete solutions for monitoring and batching applications.


These flowmeters feature new clamp holder design for quick exchange of the Equflow disposable PVDF or PFA turbine flow sensors. These sensors have low flow capabilities useful in a wide range of flow processes.

The idea is to enable fast exchange of the flow sensor in single-use applications. Typical applications are found in clinical, analytical, bio-tech and pharmaceutal chemistry equipment, where frequent tube
changes are neccessary to avoid contamination of the process.

Despite the term “disposable”, these devices are also suitable for long-term measurement. Options include alarm, programmable K-factor and batch functions.
