Reference Number cb-904-13063031 The following requirements are the mandatory technical evaluation criteria which will be evaluated during the Bid Evaluation. In addition, the Contractor will be required to meet all of the mandatory technical requirements for the duration of the Contract. Bidders are requested to cross reference the mandatory technical criteria in a concise format by using page, paragraph(s) & sub-paragraphs as applicable to their supporting technical documentation. The High Accuracy Natural Gas Meters must meet all of the following mandatory technical evaluation criteria. Bidders must demonstrate their compliance with all of the following mandatory evaluation technical criteria by providing substantial information describing completely and in detail how each requirement is met or addressed. M1 The meters must have mass flow rate as their primary measurement i.e., the meters must be mass flow meters and not volumetric flow meters. M2 The meters must have an accuracy spec of 0.5% of reading on or above 50% of the full-scale range, or better. M3 The meters must be calibrated using Methane for a Natural Gas application. M4 The meters must be calibrated for their entire range with a maximum mass flow rate of 0.016 kg/min at line pressure of 2.07kPa and 15 degrees C. M5 The meters must be in-line and have a 1-inch NPS MNPT 316 SS connection for a 1-inch nominal black iron natural gas pipe. M6 The meters must employ a drift-free sensor that does not require the meter to be sent out for yearly calibration with the ability to validate the drift free sensor in-situ by the end user i.e., with instructions and software to perform validation. M7 The drift-free sensors’ performance must be backed by a warranty that covers deviations that result from regular use during the life of the meters. M8 The meters must have flow conditioning built-in and must not require more than 3 diameters of straight pipe run upstream and downstream. M9 The meters must have a turndown ratio of 100:1 or better. M10 The meters must have a response time of 3 seconds or better to achieve 63% of the final value (one time constant). M11 The meters must be cFMus approved for Class 1, Div.1, Groups B, C, D. M12 The meters must employ Modbus RTU communication protocol over RS-485, to provide measurement data digitally and should include a flow totalizer.
