Digester Gas is an important byproduct of water and waste treatment. Measured for environmental reporting, it is also monitored when used to provide power for the treatment plant operations. Eldridge Products Inc.’s Master-Touch thermal gas mass flowmeters are calibrated with a CH4/CO2 gas mixture for the best accuracy. With no need for temperature and pressure corrections, Master-Touch flowmeters further reduce operating costs. For more information, call 800.321.3569 or visit www.epiflow.com.
