SWE + ice and water contend: SPA– Snow pack analyzer
Prediction of runoff No ice bridging effect SWE, snow-depth, snow density, liquid water and ice
contend
Snow melting (Runoff): SMA-Snow melt analyzer
Prediction of runoff Simple and easy installation SWE, snow density, liquid water and ice contend close to
the ground
Monitor environment: AWS – Automatic Weather station
Heavy duty weather station for high alpine areas More than 30 years experience Complete system out of one hand (Steel construction,
sensors, software and know how)
Ice risk detection: IDS 20 – Ice detection sensor
Internal plausibility check (dew point/frost point , temp.) Easy integration in existing systems Different sensors for different applications (Airports,
Antennas in mountain areas, power lines, wind turbines)
Our devices can measure:
Discharge mountain rivers: TQ - Tracer
Mobile discharge measurement device No cross section needed Validation unit for already installed systems
Discharge for rivers and channels: RQ-30 – 15m / 35m
Stationary non contact discharge measurement device Maintenance free Easy installation, because outside of the water
Water level: RL – 15m / 35m / 75m /120m
Non contact Maintenance free Independent of ambient conditions because of radar
technology
Hydrology
Our devices can measure:
Discharge for rivers and channels: RP-30
Mobile non contact discharge measurement device Use on Handrails, cable ways and on a Tripod Alternative to ADCP boat and propeller measurement
when cross-section known.
Discharge in open channels and sewer systems: SQ – 3m / 6m / 8m

certain condition) Easy integration into existing control systems
Hydrology
SOMMER is the global leading None contact radar
based solution provider for measuring discharge
and has more then 15years expiriance
in applications
all arround the world with 1000 nd‘s of units
installed arround the globe.
SOMMER developed
a special complex
model revolutiionising and
making it to the most advanced
company in measurinig
contact free discharge and flow.
Discharge Measurement
Non-Contact Radar Sensors
Stationary RQ-30 Mobile RP-30
Sommer Sensor is tested by METAS swizerland in subject to accuracy and certified accordingly
Water level (stage)
Transit time measurement
Reflected ultrasonic/radar pulse (26 GHz)
Vertical to water surface
Time between transmitting and reflecting the pulse = directly proportional to the distance
Radar: independent of air temperature and medium (e.g. foam)
Flow velocity
Measurement of Doppler frequency shift (Doppler Effect)
Radar impulse (24 GHz) is reflected by water surface
Frequency shift by movement on the water surface (min. swell 3mm )
Measurement of surface velocity, calculation of mean velocity with hydraulic model
SQ Flow Meter - Measurement Principle
Discharge calculation
Continuity Equation: Q = vm * A(W) Q = volume flow in [m3/s] vm = mean flow velocity in [m/s] and A = wetted cross section in [m2]
Mean velocity vm vm = vl * k
vm … mean velocity vl … local velocity
k … calibration coefficient
k-factor is depending on the site characteristics
Automatic k factor calculation is done with hydraulic model (e.g. Manning or Strickler)

Why measuring discharge in sewers?
Data are most important for : Communities
Hydraulic analysis and capacity studies for the sewer network and pumps Storm water management/ monitoring of overflows Allocation of costs
Waste water treatment plants
Inflow and outflow monitoring Daily discharge values
Industry
Treated waste water amounts released to rivers Cooling Water collection from power plants …
How are data collected ? Fixed measurement networks of waste water management agencies for
communities (storm waters, sewers or combined sewer lines) Permanent installations for waste water treatment plants and industry Temporary measurement campaigns for network capacity evaluation
Permanent flow measurement – methods
Filled pipes MID Ultrasonic clamp on Submerged ultrasonic mouse Partially filled pipes Submerged ultrasonic mouse Inverse sewer obstacle (built in
flumes/weirs venturi, aso) All methods are Costly installations Submerged in the sewers Contact measurements Maintenance intense (!) Reducing sewer capacity
Non-contact flow measurement with radar
