Cycle rate: The number of sampler cycles per minute is set by adjusting the dial on the sampler controller . Turning
the black controller knob adjusts a timer that determines the cycle rate .

Sampling time: This is generally “pumping time .” Keep in mind that sample portions are collected only when
product actually is in front of the sampler .
Pump Flow Factors
While a truck pump is rated at units of flow per time interval (gallons per minute, liters per minute, etc .), actual delivery
will be influenced by many factors, some of which are:
Speed of pump drive and pump condition
Type of valve on farm tank
Suction hose size and condition
Head pressure, suction and discharge
Since some of these “flow factors” are beyond the scope of the sampling system itself, an operator may require a few
days of using the system to become familiar with its characteristics and how it operates on individual producer farm
tanks .

NOTE
To take more sample, increase the sample frequency by turning the sampler controller dial counterclockwise, towards “+” . To
take less sample, decrease the sample frequency by turning the sampler controller dial clockwise, towards “-” .
