It can be very expensive to confuse Delta Flow VS Delta Pressure

1. Flow:
Volume over Time
Gallons per seconds
Liters per seconds
Even mass Velocity:
Pounds per second
"Kilos" per Second

Flow Fluctuation

is expressed in %age +&- variation on average velocity

IS not

Can not be

Force: Mass on Area
Pounds per square inch.
Kilograms / sq. centimeter
Mass on area:
Pounds / in2 "PSI"
Kg Cm2 (approx. = "Bar")

Pressure Pulsation

expressed as amplitude at frequency
+&- PSI / cyclec/sec or Bar @ Hz.

First consider flow & pressure in the same terms.
VELOCITY, - distance over time.

3. Mass of liquid in a pipe is transferred at not above 180 inches/sec or say 460 cm/sec
Pressure in a fluid travels at, Mach 1 (in Air)
In harder substances (liquid) is transferred at up to 4000 MPH, or say 140,000 cm/sec.
"Flow is 300 times slower than pressure".
So there is time to flow up, stop, turn around, and flow back out again.


On the other hand, what ever the residual pressure pulsation is will flu straight past a "T" in a split thousandth of a second.

CONCLUSION:- With 300% greater efficiency, because flow and pressure pass through a PULSEGUARD DAMPER you have increased performance at lower cost.
Dampers that do, flow goes through, but pressure pulsation does not.
