Liquid Level Detector

Liquid level detector not detecting liquid level

•Ensure that the level sensing cables are plugged in.

•Check sensitivity setting in the 215 Setup Utility (see page 3-9) and lower the percentage.

•Check if liquid is detectable. Liquid level detection works only if there is electrical conductivity in your liquid. Liquid level detecting will not work with most non-polar liquids. For intermediate polarity liquids and polar liquids, check the sensitivity setting in the 215 Setup Utility.

•Call Gilson if this is caused by faulty circuitry.
