Through Flow Sampling with the Twin Port Pocket Pump
The 210-1003MTX twin port Pocket Pump is designed for through flow applications such as bag sampling.
Refer to the pump diagram on page 8 for identification of the inlet and outlet ports.
1) Constant flow mode sampling
Constant flow mode compensation performance:
The pump flow rate will be within ±5% at flow rates
up to 200 ml/min, inlet back pressure up to 20 inches of water and outlet pressure up to 3.0 inches of water
maximum.
To set the pump up for constant flow mode bag sampling applications:
Ensure that the pump is set to Constant Flow mode and that the battery is fully charged.
Determine the required sample volume and sample duration. The required pump flow rate can be calculated:
Flow Rate = Sample Volume ÷ Sample Duration
Connect a flowmeter such as a 393 series rotameter to the inlet of the Pocket Pump.
Press [ ] to start the pump running.
Press . The LCD screen will show the flow rate setting screen with ‘
SET
’
flashing. Use the and buttons to set the required flow rate in millilitres per minute
on the LCD screen.
When the required flow rate is set press the button to display the flow rate adjust
screen, with ‘
ADJ
’ flashing.
