NEW SQ SERIES FLOW METER FOR SEWAGE AND WASTEWATER
|
|
|
Following the remarkable success of the Sommer RQ-30 Radar Discharge Sensor for rivers, streams and canals, the new SQ Flow Sensor
now brings a cost effective, non-contact solution to the wastewater industry.
The SQ has an impressive list of features including no scheduled maintenance, best in class accuracy, non-contact reliability, resistance to acids and corrosive gases and a fully watertight flood proof housing. With an extensive feature list, low cost of ownership, combined with excellent reliability, the SQ is sure to become a Sensor of choice for wastewater professionals.

Flow monitoring in process, cooling, wastewater or any other industrial effluents running in open channels and semi-filled pipes has just become a whole lot easier. The new Sommer SQ Flow Meter can be used for liquids of different consistency or viscosity, for hot water as well as for aggressive environments, due to its innovative non-contact sensor harnessing the power of both radar and ultrasonic technology.
The radar sensor of the SQ provides continuous and non-contact measurement of the discharge (flow) volume of sewer systems, ducts, semi-filled pipes and other technical channels in the fields of wastewater and industrial effluents. Due to the contact-free measurement, deposits and other solids in the water do not degrade the sensor, making it especially advantageous for the measurement of wastewater. The compact design allows an installation in manholes or in sewage systems.

NO CONTACT...NO MAINTENANCE
|
|
- SQ Sensor automatically computes discharge (flow) from Velocity & Level
- No structural work necessary in the water
- Simple installation and integration in existing measurement and process control systems
- Data output via multiple interfaces: RS 485, Modbus, SDI-12, Pulse signal, Analog
- Uninterrupted accuracy - measures with high turbidity and solid contents in the wastewater
- Measures even at very low discharge rates
- 3 models available for different water levels: SQ-3, SQ-6 and SQ-15
- Watertight, floodable and resistant housing
- Suitable for installation in aggressive environments
- Integrated hydraulic model for precise discharge calculation
- Measuring range: water level 10 ft, 20 ft, 50 ft; velocity 0.3 ft/s to 50 ft/s (depending on the flow conditions)
- Velocity Sensor tested by USGS Hydrologic Instrumentation Facility (HIF)
- Velocity Sensor independently certified by METAS (Federal Institute for Metrology, Switzerland
- Optional: non-contact measurement of water temperature

The SQ Flow Meter is suitable for a wide variety of applications in the fields of waste and process water including discharge measurements in sewer systems, wastewater treatment plants, channel systems, ducts, semi-filled pipes and other technical bodies of water.
It is important to monitor the flow rate at the inlet of a sewage treatment plant to be able to regulate the different processes and systems or to allocate the costs in wastewater associations. Similarly municipalities or local water authorities need to measure duration and frequency of rain and flood events in order to manage their storm water channels most efficiently. At central measuring locations in the rainwater sewer system and/or at rainwater overflow basins, the amount of water and discharge rates can be determined.

Due to the SQ's compact design and flexible mounting options, the sensor can be installed very easily. It can be fixed underneath a bridge or crossbeam, on the ceiling of closed channels, or in a service manhole of sewer channels. Moreover, the SQ is equipped with a mounting cube that allows vertical / horizontal flexible mounting options. Due to the non-contact measuring technology the system is installed outside the body of water. This is a big advantage as the sensor does not accumulate deposits or become soiled as with submerged devices. As a result, the system remains maintenance-free and easy to access.
For installations in sewer manholes, a variable adjustable mounting device can be supplied with the SQ sensor.

SQ FLOW METER AS MOBILE STAND-ALONE STATION
|
|
For remote measurement sites without a permanent power supply and hardwired data connection, the SQ can be equipped for remote operation. Incorporating data logger and data transmission technology (2G/3G/4G modem) together with a strong battery pack, the SQ becomes a reliable self-supporting and independent system ideally suited for local or remote measurement stations. Additional options for the system include a solar panel for continuous long term operation and a camera for real-time visualization of the site.
