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.

Reliable and accurate flow rate measurements

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.

Features

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.

FAQ

Which media can be used for the measurement?

The measurement performs most effectively with water. Methanol and ethanol are also suitable media.

How frequently does the flowmeter need to be checked?

If you are using the flowmeter as a testing device, we recommend sending the device for inspection once a year. This will ensure that the measurement results are correct.

Which testing standard is used to check the flowmeters?

The flowmeters are checked according to a special DURATEC work specification. The test equipment used for this process is traceable according to DKD or NIST.
