YK-D65 Grouting Recorder: Multi-Channel Grouting Construction Parameter Real-Time Monitoring and Recording Integrated Solution
Product Structure and Design Features
The Nexisense YK-D65 Grouting Recorder adopts an industrial-grade integrated design, with a built-in high-precision sensor module. It supports flexible configurations of 2 channels, 4 channels, and 8 channels to meet the needs of single-hole, multi-hole, or multi-pipeline synchronous monitoring. The instrument operates on AC220V±10% power supply with a power consumption of 60W, adapting to most construction site power supply conditions.
The core measurement unit includes flow sensors, pressure sensors, and density sensors, combined with a high-sampling-rate data acquisition system to achieve synchronous real-time collection of flow, pressure, density, and water-cement ratio. The screen adopts a large touch screen input method, supporting mixed text and graphic display to intuitively show instantaneous values, cumulative quantities, pressure curves, and process trends of each channel. The instrument can be optionally equipped with an A4 inkjet or laser printer, allowing on-site instant printing of construction reports to meet the immediacy requirements of project acceptance.
The system achieves long-term stability of 0.25% FS/year and operates in an environment with humidity of 0-90% RH, ensuring stable operation in humid, dusty underground projects or outdoor construction environments.

Operation Interface and Core Functions
The YK-D65 adopts a touch screen input method with a clear and intuitive operation interface. It can simultaneously display multi-channel instantaneous flow, cumulative grouting volume, real-time pressure, slurry density, and the calculated water-cement ratio. The graphic display module draws pressure-flow-time curves in real time, facilitating on-site judgment of grouting diffusion and plugging effects.
The instrument supports automatic data recording and storage. The recorded content includes key parameters such as project number, hole number, time, pressure, flow, density, and water-cement ratio. On site, standardized construction record sheets can be directly output through the A4 printer to meet the original data retention requirements specified in the standards. The system reserves communication interfaces and supports industrial protocols such as Modbus-RTU, facilitating integration with PLC, SCADA, or engineering management information systems for remote monitoring and centralized data management.
Typical Application Scenarios and Project Integration Cases
In projects such as curtain grouting of water conservancy dams, backfill grouting behind tunnel linings, water-stop grouting of foundation pit enclosure structures, and synchronous grouting of subway shield tunneling, the YK-D65 can monitor changes in grouting parameters in real time, guiding construction personnel to adjust slurry mix ratios, grouting pressure, and flow to avoid quality hazards caused by under-grouting or over-pressure.
In a certain high-speed railway tunnel grouting reinforcement project, after integrating the 8-channel YK-D65, the construction team could synchronously monitor the multi-hole grouting process, automatically record the cumulative volume and pressure curves of each hole, significantly improving grouting uniformity and construction efficiency. The acceptance data was directly exported as completion documents. In another foundation pit project case, the system was linked with the grouting pump group, achieving automatic pressure overrun alarms through Modbus output to ensure construction safety and process controllability.
The multi-channel configuration is particularly suitable for group-hole grouting or cyclic grouting processes. It can flexibly switch monitoring modes to meet construction requirements under different geological conditions.
Selection Guide
When selecting, focus on the number of construction channels: 2 channels are suitable for single-hole or small-scale grouting projects; 4 channels are suitable for medium-scale reinforcement projects; 8 channels are recommended for large tunnels, dam bodies, or group-hole grouting projects. The flow range of 0-100 L/min can meet the needs of most cement-based or chemical slurry grouting. Higher flow can be customized if needed.
The pressure measurement upper limit of 10 MPa covers conventional high-pressure grouting scenarios. The density and water-cement ratio functions are particularly suitable for precision grouting processes that require strict control of slurry mix ratios. Projects with high on-site printing requirements should prioritize the A4 laser printer configuration to adapt to dusty environments. The final selection needs to be evaluated in combination with engineering geological conditions, grouting process types, and data integration requirements.
Integration Precautions
During installation, sensors should be placed close to key nodes of the grouting pipeline to ensure the shortest signal transmission path and reduce delay and interference. Power supply access should adopt voltage stabilization measures to avoid the impact of voltage fluctuations on the construction site on measurement accuracy. When integrating communication, the Modbus-RTU address and baud rate must match the host computer. Shielded cables are recommended to improve anti-interference capability.
During long-term use, regularly check the sensor sealing and zero-point drift, and use the system's self-diagnosis function to verify channel consistency. Data export and backup should be incorporated into the project quality management system to ensure that all records meet engineering acceptance and audit requirements.
