FAQs
Frequently Asked Questions
MD1 Specifications
-
What does Hz mean? “pulses per second,” “frequency,” or “Inside Diameter”.
Hertz (Hz) is unit a measure representing cycles per second (1/sec). For flowmeters, this correlates to pulses/second. The flowmeter will produce a frequency of pulses per second, where each pulse is equal to a certain volume of solution.
-
What is standard pumphead connection type? Are other options available?
Std connection type is 3/8″ od tube compression. Optional Kit-C5M = 1/2 mnpt, Kit-C5B = 1/2″ hose barb.
-
Max Feed Rate listed is 7.7 GPH. My output is a lot less. Why?
The maximum feed rate of the pump is determined by pumping water at a temperature of 72°F into the atmosphere, with a 5-foot suction at sea level. However, factors such as viscosity, elevation of operation, suction lift, fluid temperature, and injection pressure can affect the actual feed rates. To accurately calibrate the pump to the specific installation conditions, it is recommended to conduct a volumetric test.
