System truck mounted concrete admixture dispenser

The TM-CAD40 standard device is consisted of:

• Steel frame and tank support. The frame is made of galvanized metal sheets, painted with electrostatic paint. It is designed for quick and easy fixing on the truck through 4 vibration mounts. The tank is held on the frame in such a way that prevents it from being detached, even under extreme driving conditions or terrible road conditions. All hydraulic, electrical, and electronic components are carefully installed and protected in a chamber inside the frame. Indicators and buttons for manual operation are panel mounted on an inclined surface that can be removed by screws. All instruments are accessible from the front without the need of removing the tank from its base (frame). On the back side of the base, an industrial plug is installed for all electrical connections, while a quick connector is located to connect the hose that drives the chemicals inside the mixing drum.
• Pump suitable for corrosive liquids with high viscosity. Operates using suction and is able to pump even with air bubbles inside the tank. The parts of the pump that come in contact with the chemicals are made of materials with maximum corrosion resistance. The pump has low power consumption and does not affect the vehicle battery performance. Its supply varies (15-22 lt/min) depending on the viscosity of the chemical and the maximum pumping height (pump’s head is 6m).
• Electronic metering unit, suitable for viscous and corrosive materials. Measuring accuracy ± 2% with a readability of 20 ml.
• Digital indicator for displaying the amount of additive poured on site. Programmable set point of the desired quantity with relay output 16A. Integrates with other devices via RS485 Modbus. 7-segment LED display viewable even in bright lighting conditions. IP65 sealing through an additional cover with a door that allows access to the indicator’s buttons.
• 2 illuminating metallic buttons, ON-OFF and START, waterproof IP 65.
• Level gauge that indicates digitally, the percentage of the remaining additive inside the tank. IP 65, can optionally communicate via RS485 with other devices.
• 40 lt capacity polyurethane tank, with UV protection to withstand long-term exposure to the sun. With a large screw cap on the top to easily fill the tank by any method. Automatic ventilation valve that also prevents overflow. The tank has embedded carrying handles for easy transportation, steel frame and tank support. The frame is made of galvanized metal sheets, painted with electrostatic paint. It is designed for quick and easy fixing on the truck using 4 anti-vibration mounts. The tank is held on the frame in such a way that prevents it from being detached, even under extreme driving conditions or terrible road conditions. All hydraulic, electrical, and electronic components are carefully installed and protected in a chamber inside the frame. Indicators and buttons for manual operation are fixed on an inclined front panel, removable by screws. All instruments are accessible from the front without the need of removing the tank from its base (frame). On the back side of the base an industrial connector is available for the electrical connections while a quick connector is there to connect the hose that will rinse the chemical inside the mixing drum.
• Dimension and weight: 42 x 47 x 75 cm (LxWxH) / 14 kg Empty - 60 kg Full

• Recording the quantities of admixtures the driver unloads at the site. Wireless transfering of data to a cloud database in order to be accessible by other applications, like dispatching and accounting software.

The following hardware and software is required:

- GPMATIs Truck Controller that is specially designed by PROTEM for mixer trucks to collect data from up to 4 TM-CAD40 devices. Also, the controller depending on the customer’s choices, can be connected to additional sensors that must be installed on the truck and can detect: a) mixer’s drum rotation speed and direction, b) ambient and concrete temperature.
- Android based Tablet or smartphone that communicates wirelessly with the GPMATIs Truck Controller. Must be connected to the cloud via 4G or 5G mobile data.
- Betolink GPMATIs mobile app, running on the tablet or smartphone and allowing recording of admixture quantities dosed on site in a data base.

• Monitoring and ensuring that after the admixtures are added on the project, the concrete will be well mixed according to the regulation (at the intended rotation speeds of the drum and for the specific mixing time).

The following hardware is also required for this specific feature:

- Drum rotation sensor. It consists of 2 waterproof magnetic proximity sensors, 5 magnets and the necessary mounting accessories. It is suitable for applications in mobile machines, operating in extremely demanding industrial environments, highly resistant to impacts, shocks and vibrations.

• Automatic concrete temperature measurement during unloading. Additionally, a second temperature measurement can be taken by the driver, by dipping a portable temperature probe inside the on-site concrete specimen. Concrete temperature measurement can also be registered manually by the driver in our system, just in case he uses simple hand thermometers.
• Registers the specimen (cubes) taken on site by the drivers, eliminating the risk of missing cubes as well as the labor cost for duplicate data entries to other software.

The TM-CAD40 can be placed on any horizontal surface measuring 42 x 47 cm, such as truck steel fenders, and is fixed by 4 vibration absorbers with male threads and nuts. The only tools required are a drill to make 4 holes and a wrench. As for its electronics, a power supply line from the truck's battery is necessary for the device. Finally, a flexible tube must be connected between the device’s output and the mixer drum’s input.
