Open Channel Measurement

So what are the costs ?

Delivering Efficiency to Severn Trent


An example of how we at NIVUS were able to help resolve not only an application problem

but furthermore a costing problem atSevern Trent Wanlip STW

Project kept getting delayed due to project costsTo use normal flow meters, flumes or mag meter meant a dramatic change to the layout of the works and the civil costs were vast

Problem

SolutionBy using NIVUS flow meters incorporating a winch system no change to the works layout was needed this in turn gave a project SAVING of over £0.5 Million

A Partnership to find the solution

Open Channel Flow Monitoring

No need for a Flume / Venturi

•What is the cost of a Flume ?•What is the cost of installation ?•What is the annual maintenance cost ?

How do NIVUS do it ???

So what are the costs…

Flume Cost Flume 6m x 400mm wide approx. £12,000Installation 2 men 2 daysOver pumping required to keep channel dry

NIVUS CostNivus Flowmeter approx. £5,000Installation of sensor & Transmitter 1 man ½ dayOver pumping 1 hour.

So what are the costs ?

Part & Fully Filled Pipe Measurement

No need for a Mag Meter…No need to replace a Mag Meter

•What is the cost of a Mag Meter •What is the cost of installation

???

Replacement Costs

A MID with a diameter of 700 mm had to be replaced.

Old MID

OCM Pro pipe sensor with ball valve

• Mag meter cost £ 2,000• Installation Cost £ 20,000• Pipe needs to be shut down• Crane required

NIVUS Pipe sensor cost £3,000Installation 1 man ½ dayNo pipe shut down

Sewer Flow Monitoring


Sewer Monitoring

NIVUS provide sewer monitoring companies with our PCM PRO portable Flow meters for sewer surveys.

We supply one UK company with over 200 portable units as Thames Water require greater accuracy and data.

Data Management


Data Connection

• Very long battery life.• Parameters can be set remotely.• Connection to measurement data via

the Internet.• D2W Internet portal.• Can be used in Ex Zones 1 & 2• Alarms.• Reporting.• Control.• Export data to interface with other

Systems.

Cross Correlation ProfilingHow do we measure so accurately ?

Single path measurement Multi path measurement

Cross Correlation Principle


• One of the most modern and efficient measurement principles to understand the flow velocity is the Correlation Principle.

• (Correlating two similar picture samples). For this application is that the reflectors (particles, minerals or gas bubbles) are available in the medium.

• Then through a transmitted ultrasonic pulse and the received echo, they become stored as received echoes or pictures.

• By correlating both stored signals familiar reflectors are recognised. Since the reflectors move with the fluid their different positions are visible or measurable in both pictures.

• The flow velocity of the fluid can be calculated from the reflector’s progressive movement by taking into account the transmission angle of the ultrasonic signal and the pulse repeat rate.
