Flowmeter FAQ 5

Q: I noticed that my TESTA #flowmeter shows negative flow rate values. How is this possible?

A: our flowmeters are by design bi-directional. This means that they can measure the flow in both directions. If the displayed is negative, then your device is incorrectly connected in reverse to the designed direction of flow. Please note the negative values are valid measurements but not calibrated.

Ensuring the accuracy of your dispensing system.

Dissolved gases are well known to have an impact on the performance of reagent dispensing pumps. A common solution to address this problem is to install a vacuum degasser on the inlet side of the pump. However undissolved gas bubbles pass through largely unaffected by the degasser which can lead to unreliability in dispensing volumes. Several companies are now using our Solvent Line Monitor to detect undissolved gas bubbles in real-time. The digital output from the device detecting an undissolved gas bubble is being used to stop the dispensing pump before it can affect dispensing #accuracy.
