FlexGylle Features

The FlexGylle concept monitors one or more slurry tanks for seepage, leakage, sudden release, and overfilling. A pressure transmitter is installed in each slurry tank and constantly registers level changes in the slurry.

When a release is registered, messages can be sent to one or more users by SMSSMS is a text message that can be sent or received with a mobile phone., email, or voice call.

If the supply voltage is lost, FlexGylle immediately sends a message and continues on the internal battery. Monitoring is switched off, and the level measurements are frozen until the supply voltage is connected again.

Methane monitoring can reduce false alarms. During slurry storage, gas bubbles can form and affect the measured level. Activating methane monitoring helps handle this condition.

Monitoring can be temporarily disarmed when the slurry tank is emptied or stirred. Disarming can be done with a button or by sending an SMS.

For remote slurry tanks without a power supply, a FlexGylle solar-cell system can be installed.

Bottom sludge can be handled in the setup. The FlexGylle pressure transmitter is placed above the bottom sludge, and the bottom-sludge thickness is configured.

FlexGylle constantly registers the slurry level. As the level rises, the system automatically sets a new setpoint.

If the level falls below the setpoint, a message is sent. Each time a message is sent, the system sets a new setpoint. If the level continues to fall, the alarm repeats until the system is disarmed or until the level stabilizes.

The drawing shows an example of how a slurry tank is typically configured:

• The physical tank height is 4 meters, and the diameter is 10 meters.
• A 0-6 meter pressure transmitter is used.
• The pressure transmitter is lowered to 0.5 meters above the bottom.
• Bottom sludge is configured to 0.3 meters.
  • The bottom sludge is included as a constant volume in the total volume calculation.
• The floating layer is estimated at 0.2 meters, reducing the maximum slurry level height to 3.8 meters.
  • The floating layer is not included in the total volume calculation.
• The alarm limit for the maximum allowed slurry level is set to 80% of the maximum slurry level height.
  • If the level rises above 3.04 meters, a message is sent.
• The alarm limit for the minimum allowed slurry level is set to 20% of the maximum slurry level height.
  • If the level falls below 0.76 meters, a message is sent.
