Probe provides highly accurate biogas flow rates in sewage treatment digesters

Photon Control’s Focus® Probe optical flow meters are successfully measuring flow rates of biogas at sewage digesters in Vancouver. The methane-rich biogas posed a problem for conventional flow meters which couldn’t cope with the low flow rates, low pressure and high humidity specific to biogas. Using optical laser beams to measure the velocity of naturally-occurring particulates, the probe enables highly accurate flow determination despite pipe vibration, acoustic noise and gas condensation. Featuring a high turn-down ratio of 1000:1, the low-cost unit provides sewage treatment autho rities with an excellent source of data to optimize their sewage digestion processes, control biogas production and reduce greenhouse gas emissions.

GF Piping Systems’ new corrosion-resistant Type 568 lug-style butterfly valve is intended for dead-end service and fully pressure rated at 150 psi to allow for easy system expansion to the pipeline without system shutdown. Applications include industrial and potable water treatment, swimming pools, water parks and wastewater systems in such industries as chemical, chemical distribution, electroplating and power plants.

The valve, available in sizes 2” to 8”, offers a modular design with epoxy coated iron lug body. The wetted inner body, disc and bearings are available in choice of PVC, CPVC, SYGEF PVDF (polyvinylidene fluoride), or PROGEF® Natural Polypropylene materials to match the outer pipe material. This inter-system compatibility between the inner body material and outer pipe material provide excellent chemical compatibility throughout the system.
