Tekelek 4G NB-IoT, CAT-M1 LTE Pressure Logger
Product Information
LTE Pressure Logger (4G NB-IoT/CAT-M1)
The Tekelek Pressure Logger 4G NB-IoT/CAT-M1 is a multipurpose data logger that is ATEX certified. It is designed to monitor fuel tank levels and flow rates and communicates data to a remoteserver. This product is suitable for various industrial applications.
Product Usage Instructions
-
Unpack the product and ensure that all components are present.
-
To activate the logger, hold the supplied magnet to the indicated hot spot on the Pressure Logger. Four short beeps will beheard approximately one second apart, followed by a long beep, indicating that the logger has been activated and will now attempt
to connect to the network. -
The device emits different beep patterns that indicate its status. Refer to the table above for the different beep patterns and their corresponding definitions.
-
To fit the pressure sensor, refer to application note9-6111-xx, which can be found on www.tekelek.ie.

Thank you for purchasing the Tekelek Pressure Logger 4G NB-IoT/CAT-M1which is an ATEX certified multipurpose data logger which communicates data to a remote server, suitable for monitoring fuel tanks levels and flow rates.
Safety Information
The Pressure Logger is ATEX compliant, but if installing in a harsh, environment first check local applicable regulatory and safety guidelines to ensure installer security. Please refer to the User Manualfor more information on the warnings and hazards.
Installation
The PRESSURE Logger works in conjunction with a remote server and before installation must first be registered to this. Access to the backend server is required to verify that the unit has correctly joined the network.The following outlines the Pressure Logger mounting options. It is recommended to mount the logger vertically as shown above.
- Cable Ties – Handle mount:
- Cable Ties – Horizontal mount onto pipe:
- Cable Ties – Vertical mount onto pipe:
- Screws – Wall mount:
- Screws – Wall mounted from the rear:
- The pressure sensor cable should be installed in an orientation facing downwards.
Activation
Hold the supplied magnet to the indicated hot spot on the Pressure Logger, 4 short beeps will be heard approx. one second apart, these will be followed be a long beep which indicates that the logger has been activated and will now attempt to connect to the network.
- A series of beeps will be heard. This indicates the logger is registering onto the network.
- Upon successful registration to the network the logger will attempt to initiate a connection to the server, details of which have been preconfigured in the logger. This is indicated by higher pitched beeping.
- The successful activation of the unit is indicated by two successive short beeps two seconds apart. Once the logger has successfully connected, the server must issue the required commands to the logger to complete the activation process.
Beep Pattern

| Low beep once per second | Network Registration |
| High beep once per second | Network Registration |
| Low beep once every 4 seconds | Network / TCP Listen |
| Low beep once every 2 seconds | Re-establish Network / TCP |
| High / Low combination beep | Incoming Data |
| Low / High combination beep | Outgoing Data |
Low double-beep every 4 seconds
| Network Listen
(Data Received & Unit Active)
Low double-beep every 2 seconds| Re-establish Network
High double-beep every 4 seconds
| TCP Listen
(Data Received & Unit Active)
High double-beep every 2 seconds| Re-establish TCP
Fitting Pressure Sensor
- A 1” or 2” opening is required to fit the pressure gauge. In the example shown a 2” NPT opening is assumed. Note: other adapter types are possible – consult factory for further options.
- Insert the 2” to 1” NPT adapter. Ensure that it is rightly sealed and watertight. PTFE tape can be used to ensure a good seal.
- The Pressure logger sensor comes fitted with a 1” NPT adapter and a ½” NPT cord grip cable adapter. The pressure sensor fits through the 1” opening and is placed into the tank.
- The 1” adapter is tightened into the 2” adapter and the pressure sensor lead fed into the tank until the bottom of the sensor is positioned approximately 50mm above the bottom of the tank. The cable grip is tightened (torque 1-8 to 2Nm) around the cable to hold it in position.
- A connection to the chassis ‘ground’ of the tank is recommended for equipotential grounding for ATEX applications. An M4 stud connection is provided ; with an M4 nut and washer to facilitate a Connection.
- The logger has a vent plug to equalise the internal pressure in the enclosure to the external ambient conditions. For correct operation ofthe pressure probe, this vent should not be blocked by immersion in liquids etc.
