The Dalco Flow DFMa ultrasonic flow meter accurately measures liquid output specifically for metering pumps.
It is possible to specify the instantaneous flow rate and integrated flow rate, and output the instantaneous flow rate as a pulse signal or analog signal.
Integrating the Dalco Flow unit with select ProMinent metering pump models establishes a closed-loop feedback system. By transmitting continuous flow measurements directly to the pump controller, the system automatically dynamically adjusts stroke frequency to regulate fluid discharge with high precision.
Models that support feedback control
Gamma X
Gamma XL (Delta)

Mechanism

An ultrasonic flowmeter that uses the pulsation peculiar to a metering pump.
– Measurement is possible even if there is a large flow, pulsation, dirt on the liquid, _or viscosity.
– No metal is used in the wetted parts, _and even low-conductivity liquids can be measured.
* However, it cannot be measured in the case of non-pulsating flow, mixed turbidity, _or mixed air bubbles.
