We are in the field 24/7, so you don’t have to be.

Storm events don’t always happen Monday through Friday from 8:00 to 5:00. While we can’t control when the next storm will hit, we can ensure you’ll have eyes in field when it does.

Storm EventsStormwater Monitoring


Whether it’s while you are out to dinner with your family, attending your daughter’s dance recital, or even sound asleep in the middle of the night, we’ve got you covered. From water quality and level, to flow, velocity, and rain, In-Situ has a solution to make sure you capture every storm event as it happens, every time.

Real-Time Solutions For All Your Stormwater Monitoring Needs

WATER QUALITY: Aqua TROLL 600 Multiparameter Sonde

Reduce costs, extend deployment times, and improve compliance with continuous stormwater monitoring using the Aqua TROLL® 600 Multiparameter Sonde. Internal data logging, 9+ month battery life, drift-resistant sensors, and active and passive antifouling systems ensure years of performance. Simple telemetry setup with real-time information and alarming, smartphone app control, and a quick-read LCD status screen make maintenance and deployment fast and easy. Integrate with the MACE FloPro XCi to measure velocity and flow as well.

WATER LEVEL: Level TROLL & Rugged TROLL Data Loggers

Stormwater environments are often harsh and unforgiving, requiring your equipment to not only be accurate and reliable, but also rugged enough to withstand the flowing water and heavy storm impacts. Wherever you’re monitoring water level in your stormwater management program, the Level TROLL and Rugged TROLL Data Loggers are designed to perform in extreme conditions. In-Situ water level loggers are accurate, cost-effective, and are offered in vented and non-vented configurations.

VELOCITY AND FLOW: MACE FloPro XCi and Doppler Area/Velocity Sensor

Stormwater pollution, protection, and mitigation can only be effective if the storm water flows themselves are monitored and quantified. Typically, stormwater is conveyed through open channels and partially full pipes. The MACE FloPro XCi is ideally suited to measure these flows. The often turbulent flows with high levels of suspended solids are perfect for MACE Doppler ultrasonic flow measurement. Combined with a downward looking ultrasonic depth sensor, storm flows up to 10 m/s (33ft/s) can be accurately measured.

Additionally, with the Input/Output capabilities of the FloPro, key stormwater quality parameters including DO, pH, and turbidity can be seamlessly integrated and measured using the Aqua TROLL 600 Multiparameter Sonde. Add a MACE WebComm card and you can not only access and set alarms for your data 24/7 on the MACE website, but also via HydroVu Data Services.

REMOTE MONITORING: Tube/Cube Telemetry and HydroVu Data Services

Easily store and access all your stormwater monitoring data in one central, cloud-based location via native integration with In-Situ and MACE instruments. Our robust and cost-effective telemetry and data services communication system is second-to-none, offering one solution for your stormwater quality, level, flow, and rain data. With real-time feedback on all your water monitoring sites, you have eyes in the field 24/7 from the convenience of your mobile device or computer.
