Overview

LaserFlow Non-contact Velocity Sensor

Advanced laser Doppler technology for non-contacting area velocity flow measurement

The new ISCO LaserFlow Flowmeter is the first non contact open channel flow meter to use doppler velocity technology with integrated ultrasonic level sensor to measure flows in culverts, sewers and open channels. The LaserFlow uses a laser beam to measure velocities below the water surface at either single or multiple points. The obvious advantages of this new technology are set to completely revolutionise the world of flow measurement in wastewater and open channel flow applications.

The ISCO LaserFlow is perfect for a wide range of wastewater flow applications. The LaserFlow can be utilised either as a permanent or portable flow meter. The flow meter can be connected to the permanent ISCO Signature flowmeter to provide permanent discharge compliance monitoring or to the portable ISCO 2160 LaserFlow module for flow surveys and permanent installations. The flow meter continues to work even in submerged conditions by using the optional doppler ultrasonic area velocity flow sensor.

Installation is both quick and easy. With the LaserFlow's specially designed mounting bracket, it is possible to install or remove the sensor from above ground, therefore eliminating the need to enter confined spaces. With external communications protocols it is easy to attach an external wireless telemetry system to retrieve data on a regular basis. As with other ISCO flow meters, it is also possible to retrieve diagnostic data to support the actual flow measurement data.

Single- or Multipoint Measurement

The LaserFlow sets itself apart from any other flow meter with its ability to take velocity measurements at either single or multiple points below the water's surface. Multi-point velocity measurement allows a profile to be deduced and hence provide a very accurate flow measurement calculation.

MCERTS Flow Meter

The ISCO Laserflow is MCERTS certified (Class 2) meeting the Environment Agency's performance requirements. Class 2 MCERTS makes this the most accurate Doppler (non contact or wetted) based flowmeter under the MCERTS scheme for the self monitoring of effluent flow. View downloads for certificate.

FAQ's

Yes, the ordering process is very easy. Orders can be made via purchase order or by credit/debit card. Once we have the paperwork we can delivery next day to any location in Europe. Provided with the equipment is a quick start guide, and if you need extra support, the technical support engineers can be contacted via phone call.
No, all of our flowmeters are competitively priced and rental is an ideal option for cutting costs to a fraction of a full priced new flowmeter.
Every flow meter is tested upon shipping and return as part of our ISO9001 procedure. Also, as part of this procedure, the flow meter is calibrated once a year. If a copy of the calibration certificate is needed let us know.
We are here to help. If the self-help and quick start guides do not help, then call one of our technical support engineers on +44 (0) 1527 882060. We have supplied and supported many clamp on rental installations throughout Europe.
First, contact us for a quote. If you are happy with the quote then send us a purchase order. Or alternatively call us with credit card details and fill out and send us a rental agreement form.
If the stock is permitting, and all paperwork is received by 12pm then flow meters can usually be available the next day.
The minimum hire period for flow meters is one week.
Once you have the meter you can rent it for as long as you need it. However, it would help if you can let us know that you wish to extend the rental period. Upon return the meter is off-hired and once checked and tested, an invoice will be issued to you. Also, if you extend your rental past a 4, 8 or 12 week rental threshold, then you are entitled to a discount.
You are only charged for the period of time for which you have the flowmeter. So, if a flowmeter is returned 3 days late you are only charged for 3 extra days, and each of these days is charged at one fifth of the weeks hire cost.
Normally, you will use your own courier but if you have any problems let us know and we can arrange a pick up the day after you notify us, but you will be charged for the carriage and this cost will be added to the invoice.
Without exception, all our flow meters are tested. If you need a 110v plug instead of the standard 230v plug let us know.
As long as the pipe is relatively clean, coatings or paint is usually not a problem for clamp on flow meters but if the pipe is corroded or the paintwork has bubbled then a quick sanding down with sandpaper or a wire brush is recommended.
An ultrasonic wall thickness gauge, that measures to within 0.05mm, is provided as standard with all flow meter rental packages.
The screendump facility on the integrated dataloggers on all our flow meters, allows you to photograph any screen and download it to your pc.
After the equipment has been shipped, it is the responsibility of the hirer. However, in our experience it is rare that any of our flow meters are damaged. Our flow meters are tough, as well as accurate, and reliable.
