WaterWatch is an on-board monitoring device for concrete mixer trucks. Since the introduction of
BS EN206-1, the addition of water and maintaining the correct water-cement ratio has become a more critical element in the conformity of the product.
Problem
Concrete mixes are designed to a high specification, batched to a fine tolerance using state of the art technology, all ingredients closely monitored and recorded, delivered to site, then…….
The end user decides to add vast, untraceable, amounts of water to the mix to make it easier to lay!
Unfortunately this (common) practice can result in a non-conforming product with significantly reduced strength and durability properties. Retrospective compressive strength tests may fail and ultimately the supplier could receive a claim for a substandard product.

Solution
WaterWatch is a non-intrusive monitoring system which will record all on-site water added to the mix from the truck’s water tank, along with date and time of addition.
All additions are stored in memory and data may be downloaded to a PC via a USB or serial interface and saved to a spreadsheet. Over five thousand transactions can be stored in memory, after that the system will overwrite the oldest data.
Easy to install, the unit simply bolts onto the rear of the truckmixer and requires a
24 volt supply from the ignition. In our experience, the water pump systems on mixer trucks are extremely varied, so PWS has designed two versions of WaterWatch, either of which will fit the water system on your truck.
