2. System Description Dynamic response The Promag 30 measuring amplifier has a very high dynamic response of over 1000:1. It measures at medium velocities from less than 10 mm/s to over 10 m/s with the specified accuracy. When the flow is pulsating, the amplifier is not over-driven even above the end value setting at maximum speeds up to 12.5 m/s.
