AKCP Ultrasonic Fuel Level Sensor

If your business infrastructure relies on backup generators, the chances are you are also relying on fuel to power those. By using the AKCess Pro Ultrasonic Fuel Level sensor you can ensure that your fuel tanks are filled and ready for the most critical moments.

The AKCess Pro Ultrasonic Fuel Level Sensor is a liquid level detector that will monitor the level of liquid in a tank and display this level on the securityProbe 5E’s web interface and send alerts accordingly.

The RJ-45 intelligent sensor port on base unit powers the sensor. It is compatible with any of the securityProbe series units, or the E-sensor 8 expansion modules.

You can instantly be alerted should there be any drop below critical levels in your liquid. Advance alerting, including an additional feature that alerts you if you liquid level is dropping too quickly, protects you from possible fuel leaks or theft and ensure your tanks never run dry again.

The sensor assembly incorporates an advanced tank sender based on the ultrasonic measurement technology and can monitor a variety of liquids in many types of tanks. These tank level thresholds can then be linked to the advanced notification alerts on the securityProbe 5E’s web interface.

This sensor is designed for monitoring liquid levels in tanks. These tanks can be in linear and non-linear sizes as they are easily calibrated from a simple wizard that is run from the securityProbe 5E’s web interface. Linearization parameters are used to adjust the measurement accuracy for non-linear tanks. For example a tank is non-linear if the tank height is not proportional to its capacity.

The low profile design and standard SAE 5 hole mounting pattern make it easy to install and setup and it has no moving parts for long lasting functionality.

Example Uses

Rate of Change / Theft Detection
The Ultrasonic Fuel Level Sensor comes equipped with advanced rate of change detection that measures the level rate in a percentage from 1% to 50% over a period of time from 1 to 20 minutes.
You can set the direction to Up, Down, or Both and you can set the Status when the limit is exceeded to show either High Critical or Low Critical.
By linking this sensor alert to a notication you can get an SMS, E-Mail, SNMP Alert instantly. This feature is designed for our Ultrasonic Fuel Level Sensor to prevent theft of liquid or be alerted to leaks in storage tanks.
This feature is replicated in the AKCess Pro Server where many more notications types are oered so that you can alert and protect your valuable assets.

How it Works
The Ultrasonic Fuel Level Sensor Once the Sensor has been installed and congured on the securityProbe or AKCess Pro Server interface, the Ultrasonic Fuel Level Sensor works by emitting an Ultrasonic Beam directly at the liquid in use as shown in the diagram below.
Once the Ultrasonic Beam has made contact with the liquid it bounces back to the Sensor to give a highly accurate measurement. This measurement is passed to AKCP’s securityProbe Unit where is processed and transmitted directly via Ethernet or an EDGE/GPRS/GSM Modem to the AKCess Pro Server. Sudden changes in Liquid Level or Liquid Volume can be used to trigger Notications and Alerts to protect against theft and general Service Outages
