Our weir tank system is an ideal solution to measure the flow of water in open channels.
Manufactured in rigid PVC and reinforced for additional robustness, our flow measurement weir tanks include two solid external support bands to prevent bowing and distortion, with the inlet and outlet pipes able to be fabricated to suit customer requirements.
Weir tanks are ideal to provide both cost-effective and accurate flow measurements, using the technology of placing a fixed obstruction within the flow of effluent.
The system includes provision for a data logging flow meter housed in a weather-proof kiosk, a critical laser-machined thin plate weir, an upstream baffle and a maintenance drain-down valve. In addition, the outlet weir plate has additional supports so it remains free from any bowing or skew.
A weir tank within the field can typically see an accuracy rate of between +/-5-15% when correctly specified, installed and maintained. At SIRIS we can supply an off-the-shelf, fully compliant, regulatory flow measurement system that can be installed above or below ground.
A weir tank is not suitable for use where there is a high proportion of solids present within the effluent as these may stick to the sides of the weir system and crest and impact measurement and flow. In addition, low extremes of temperature where ice may form can impact the accuracy of measurement of flow.
Weir tanks can be useful in applications where flow is above ground and the flow of water is piped.
Our robust and cost-effective weir tanks offer a complete solution for both above and below ground applications.
The complete system is factory-calibrated in accordance with BS/ISO standards and requires minimal on-site commissioning.
When you invest in a SIRIS weir tank we guarantee it will be pre-calibrated at our specialist workshop to ensure it meets all regulatory requirements, including MCERTS and BS/ISO 1438. This means installation is as simple as connecting the inlet and outlet pipes, powering up and switching on – making it an ideal off-the-shelf solution.
SIRIS weir tanks are MCERTS accredited so you can be confident that the data provided is reliable and accurate forlong-term flow measurement.
All SIRIS products are compatible with our web-based data recording software, which allows quick and easy access to your data at any time – from any location.
We pride ourselves in offering a bespoke service to all of our clients. Our design and installation process ensures we provide you with a cost-effective solution tailored to suit your site’s individual requirements.
When you first contact SIRIS, our friendly team will be on hand to take your enquiry and assess your needs. We know that every site has different requirements, so we’ll work closely with you to understand your individual needs.
At this stage our wastewater management experts will provide a tailored quote for your system. For most sites we can do this using photographs, however for larger or more complicated sites we will arrange to visit you and assess it in person. If MCERTS is required we will ensure we develop a system that is fully compliant
Our team will assemble your bespoke system at our dedicated facility. We’ll also pre-calibrate any equipment that can be commissioned off-site.
We will arrange for your equipment to be delivered directly to site and liaise with your chosen contractor to advise on installation requirements. Depending on the project, we may also attend site to assist with the installation process.
Our specialist engineers will attend site to commission your equipment and check it’s working correctly. We’ll also go through your new system with you and answer any questions you have. Once we’ve completed the calibration we will be able to issue you with a CalCert which allows you to prove your site is fully compliant to auditors.
Our team is always on hand to support with any queries or teething problems you may be experiencing. For most sites we also recommend a bi-annual servicing package to ensure your equipment continues to function correctly.
All SIRIS products can be used with our data monitoring software, Palette, however they are also compatible with your existing SCADA system. Our expert team is committed to working in partnership with our customers to meet their individual requirements and ensure our products fit seamlessly into each site.
“SIRIS flow measurement weir tanks offer an ideal off-the-shelf solution for some sites. Not only are they easy to install and set up on site but they are guaranteed to meet Environment Agency MCERTS flow requirements – giving you the peace of mind that your system is fully-compliant.”
