Flowmeter d.Flow
The flowmeter is especially designed for checking the accuracy and fluctuation of HPLC or dosing pumps. The device is calibrated and traceable according to DKD or NIST.
The flowmeter d.Flow determines the actual flow rate of a liquid flow. For this purpose, the time to fill a measuring tube with constant volume is determined. The display shows the measured value and the filling level. The measured values could be logged or transmitted directly via RS232.
The measurement is volumetric by opto-electronic detection of the liquid level in a rising pipe. The time that passes between reaching a lower and an upper level is being measured and the flow is being calculated. After the upper level has been reached, the rising pipe will be drained via a magnetic valve and the measurement can start again.
Density and temperature of the medium do not matter due to the volumetric measuring principle. Due to the low surface tension, water, ethanol or methanol are recommended.
