Staff Gages Overview
Stevens’ environmentally rugged staff gages provide a quick and easy visual indicator of water level and flow. Every water level monitoring station should include a staff gage from which the height of the water may be visually and easily compared to any data logger’s reported measurement. Enamelled iron gages are preferred over other type gages (such as painted gages) since ...

Tackling rainwater shortages during dry seasons using a socio-technical operational strategy
The management of water resources during the dry season is a major challenge associated with rainwater harvesting (RWH) technology, but is necessary given the human suffering that follows from resulting conditions of water scarcity. In this study, the parameters for dry season assessment are defined in terms of ‘no water days’ (NWD) and rainwater usage ratio. A simple socio-technical ...

The Importance of Dynamic Density Compensation in Water Level Monitoring
OBTAINING SUPERIOR WATER LEVEL ACCURACY IN COASTAL ENVIRONMENTS In-Situ Inc. water level instruments measure the sum of all pressures (atmospheric and hydrostatic) exerted on a pressure transducer and use that data to calculate water levels. Water density contributes to the total hydrostatic pressure. Saltwater has a higher specific gravity than fresh water. A standard column of saltwater exerts ...

RTU based basin, canal and river level monitoring system - Case Study
Key Requirements: All installations require timely notification of rapidly changing conditions while minimising the cost of communications. Instead of the continual polling that is characteristic of SCADA systems, TBox devices use push technology to communicate only when necessary. Push technology best utilises inexpensive public networks and allows remote sites to operate on the least expensive ...

Harris county flood warning system - Case study
The Harris County Flood Control District in Texas was created in 1937 as a response to the devastating floods that struck the region between 1929 and 1935. The District's boundaries protect 3.7 million people and include the city of Houston. Twenty-two different watersheds are included in the district's boundaries, each with a unique set of monitoring challenges. The District is using the "Flood ...

ToughSonic sensors and tsunami warnings
Senix ToughSonic ultrasonic sensors play a critical role detecting sea level changes as part of a sophisticated Tsunami Early Warning System (TeWS) in the Philippines. Senix engineers collaborated with the Philippines Advanced Science and Technology Institute (ASTI) to customize ToughSonic 50 ultrasonic sensors for this first-of-its-kind water level monitoring system. Each ToughSonic 50 sensor is ...

CASE STUDIES Rapid Deployment of Hydrological Monitoring Station - Case study
Following a 3.2 magnitude earthquake on September 7th, the water level of the karst river Vrljika started dropping very quickly. This rare phenomenon has last occurred in 2004, and, before that, in 1942. Low water levels of Vrljika can be dangerous for several endemic fish species; and the whole Imotski region gets its water supply from Vrljika. Less than 24 hours after the event, Geolux ...

The best water level sensor of 2023
What is a water level sensor? A water level sensor is a device for measuring too high or too low a liquid level in a fixed vessel. According to the method of measuring liquid level, it can be divided into contact type and non-contact type. The input type water level transmitter is a contact measurement that converts the level height into an electrical signal output. It is a widely used water ...

Sewer System Water Level Monitoring
Monitoring the water level in a sewer system is crucial for efficiently managing urban water infrastructure. Real-time data is used for early warning to detect flooding and leaks. Collected data is also analyzed to provide insights on performance and enable opportunities for optimization, improving efficiency and planning future upgrades/maintenance needs. ABM's non-contact ultrasonic and radar ...

Senix sensors monitor Philippine flooding
Extraordinary flood risks require extraordinary technology A variety of factors make the Philippines, and especially the Manila region, among the most flood prone in the world. Tropical rains flow rapidly from mountain uplands to the Manila basin where dense urbanization accelerates run-off. To make matters worse, Manila is built on lowlands that are getting lower due to ground water ...

Online discharge measurement with OTT SLD
Background For the economic management of the waterways between Elbe and Oder it is essential to know the discharge of these rivers at defined locks. The authority for water and navigation (WSA) in Lauenburg operates hydrological stations for the measurement of water level and discharge to effectively regulate the water flow at the locks in Plau and Malliß (Mueritz-Elde-waterway) and in ...

Water Level Measurements-Part 1
Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

River level monitoring lowers bridge scour risk
Engineers at Transport Scotland have investigated the potential for water level monitoring systems to help mitigate risks where transport infrastructure interacts with moving water. The trial was conducted at a bridge over Vales Burn near Hawick in Scotland, and the monitoring equipment was provided by OTT HydroMet. Climate change is increasing the frequency and severity of extreme weather ...
