Modern measurement

of flow

Introduction

SOMMER was founded in 1987 and has more than 30 years of experience in developing and producing high quality and innovative measurement equipment for hydrology and meteorology.

1) SOMMER Headquarters

2) SOMMER production facility – opened May 2015

Introduction

SOMMER is located in the heart of Europa. In the border triangle of Austria, Germany and Switzerland. Sommer is active all around the world with distributers in more than 60 countries on the world.

SOMMER is a family owned company with traditional values. Customer focus, reliability, excellent service and high end products are our commitment to you. 3) SOMMER headquarters in western Austria

Beginning of the ALPS. Mostly mountainous area. In winter snow covered. Flood danger if snow melt and rain at the same time

VORARLBERG - AUSTRIA

Areas of activity

Hydrology Measuring solutions for

surface water, rivers, open channels and groundwater

Meteorology Recording meteorological data for alpine monitoring

networks, weather or avalanche warning

services with focus of snow and ice measurment

Sewers and industrial water

Non-contact discharge measurement for

wastewater, sewage systems and industrial

waters

Product portfolio

instruments are used all around the world to measure the complete liquid and frozen water cycle.

instruments are used:

Flood prediction / warning

Avalanche prediction / warning

Research

Dams / basins

Div. Industry (mining, thermal power plants,…)

Sewer systems

Storm water systems

Water Treatment plants

Irrigation

Meteorology

Snow water equivalent (SWE): SSG – Snow scale

No antifreeze liquid required Robust aluminum construction Range from 200 to 3000 mm SWE

Snow Depth: USH-9 Maintenance free ceramic Membrane Integrated Temp. compensation High power pulse for best results during snowfall

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

Stationary non contact discharge measurement device Maintenance free Easy installation, because outside of the water Mounting without entering manhole possible (under

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

RQ-30 / SQ-Series 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

SOMMER non-contact flow measurement (SQ-3, SQ-6, SQ-8R)

Relatively new measurement system

System: radar technology

Mounted outside of the water body! easy

mounting on ceiling or put into a manhole

Data set analysis

Recognition of dynamic processes in the water body

– Hysteresis

– Riverbed changing

– Super critical flow

– Tide effects

– Before the flood event the black rating curve was measured.

Blue + Green = velocity / Black + Red = Water level

– After the flood event the rating curve has changed to the red one.
