The device is heating up during the charging process. Should the SONO-DIS only function for a short period or not at all in spite of several attempts to charge it, the integrated accumulator is defective and must be exchanged. In this case, please contact our local distribution partner or us directly. -

Info By selecting this menu item you will be issued various information regarding your SONO-DIS portable measuring instrument. These are: • Serial Number • Hardware Version (HW) • Firmware Version (FW) • Accumulator Capacity • Accumulator Voltage Measuring Mode This menu enables to switch to expert mode. In expert mode, the water cement ratio (w/c ratio) will be displayed instead of the water content. -
Page 17: Concrete Specific Base Parameters
The setting of the correct raw density is important. The raw density influences the measurement of the water content inside the SONO-DIS. The difference of raw density between 2.200 and 2.300 corresponds with 8 liter water. If the raw density of the concrete cannot be determined on site, the input of the set density of the mix computation would be however a possible compromise to achieve acceptable results. -

Page 24: Correct Handling In Fresh Concrete
Correct Handling in fresh concrete SONO-WZ works with state-of-the-art TRIME TDR-method (Time-Domain-Reflectometry) based on radar technology. Plastic and liquid concretes with slump values >30mm can be easily measured with SONO-WZ. An automatic averaging with 4 to 5 single measurements ensures a procedure with representative material mix on the probes surface. -
Page 25: Measurements Of Fresh Concrete Samples In A Plastic Bucket
Not Correct! Correct! The measurement field of the probe is not completely The measurement field is completely inside the inside the material material When inserting the probe several times at the same place, there is the danger of segregation effects at this place. By removing the probe out of the fresh concrete, the space will be filled with fine and liquid particles which could lead to higher measurement values. -
Page 26: Measurement Procedure For Concrete With Slump F2, F3 And F4
NOTE: • The probes surface must be clean and free of concrete crusts and if necessary the probes surface must be cleaned with a wire brush. • The bucket should be filled minimum 30mm higher with fresh concrete than the probe length (180mm). -
Page 27: Measurement Procedure For Concretes With Slump F5 And F6
NOTE: When conducting the measurement procedure, be aware of the following rules and empirical values: 1. Never plunge the device at the same spot in the bucket 2. Delete individual measured values if they deviate significantly from the mean value. 3. - Page 28 Helpful references and findings from user practice Mixing in the laboratory: For mixing with dry aggregates, depending on the rock, a certain waiting time must be taken into account before the measurement takes place, as the saturation time depends on the type of rock. If the measurement is started too early on dry rock, the measured water content will be too high because the core water has not yet been absorbed by the rock! Subsequent adding of water in the laboratory:...

Page 29: Theory & Practice Of The Water-Cement-Ratio Determination
Theory & Practice of the Water-Cement-Ratio Determination The water / liquid proportions measured by SONO-WZ In principle, SONO-WZ measures the same proportions of water as the kiln drying method. 1. The effective water in the concrete mix is the water which is considered for the w/c ratio. -
Page 30: Using "Kiln Drying" As A Refernce Measurement
If SONO-WZ shows too high water contents in special concretes, the G-Set can be reduced by the corresponding number of liters. The exact positive or negative value to be set as G-Set can be determined in two ways: • By comparative measurements with several correct target water contents of the concrete. E.g. with concrete mixtures that were mixed with dry aggregates. -
Page 31: Measurement Of Earth-Moist Concrete
Measurement of earth-moist concrete Stiff concretes with slump values <30mm cannot be measured with the SONO-WZ by hand. They have air gaps and it is not possible to compress such concretes precise by hand. In Preparation: For this application a measurement procedure with a subsequent and defined addition of water into the earth moist concrete inside a 10 liter bucket is suggested. -
Page 32: Field Experience Example: Sampling In The Transport Concrete Plant
6.5.3 Field experience example: Sampling in the transport concrete plant Mixing time in transport concrete plants often is very short to increase the throughput. Full homogenization finally takes place during the transport in the transport truck. In this example a concrete sample was drawn directly from the twin-shaft mixer into a bucket. The sample with a normally distributed sieve line and a water nominal value of 170 liters/m was measured using the SONO-WZ with 170 liters/m... -
Page 33: Recipe Handling And Archiving
Recipe Handling and Archiving With the proper adjustment of the parameters Density, CHAR (fine, coarse, normal, special), as well as the G-Set, a good matching of the water cement ratio with the reference methods can be achieved. With repeated use of different concrete recipes and for obtaining the best possible result in accuracy, it is recommended to note the required settings of Density, CHAR, and G-Set together with the type or variety of concrete. -
