No calibrator is required as this unit can be configured via RS-232C connection ST51 Mass Flow Meter For Biogas, Digester Gas, Methane and Fuel Gases � Wastewater Treatment Plant Digester Systems � Biogas Production and Recovery — Anaerobic Digester Processes — On-Farm Systems — Fermentation Systems � Landfill Gas Recovery Systems � Co-Gen Power Systems � Coal Mine and Coal Bed Methane Recovery The Model ST51 Flow Meter is an accurate, easy to install, no moving parts solution for measuring and controlling biogases, digester gases, methane and natural gas flow. Model ST51 utilizes FCI proven thermal dispersion technology to provide direct mass flow measurement resulting in higher performance at a lower cost than orifice plates, DP, Vortex shedding and other thermal devices. Biogas and digester gas applications are challenged by wide flow variations and dirty, wet gas. Flow variation is experienced as these processes move from low production start-up phases to a consistent, sustainable process and by seasonal temperature change, where cold temperatures slow gas production and higher temperature accelerate gas production. While the primary composition of these gases is methane and CO2, residual H2S and wet vapor leave deposits and corrode surfaces. ST51 provides the solution to these challenges. It features a wide- turndown ratio, up to 100:1 and is highly sensitive to low flow measurement. To measure correctly in fluctuating temperatures, flow meters must include temperature compensation circuitry and it is standard in ST51. ST51 has no moving parts to foul or clog and is easily pulled from the pipe for occasional cleaning. Model ST51 installs in line sizes ranging from 2 to 24 inches [51 to 610mm] with 1/2” or 3/4” NPT. The Model ST51 uses precision, lithography structured platinum RTD sensors embedded in FCI’s equal mass small diameter thermowells. Combined with microprocessor electronics and precision calibration, the Model ST51 achieves excellent accuracy, fast response and virtually maintenance free operation. Biogas, digester gas and landfill gas compositions are dominated by methane (CH4) and present a potentially hazardous installation environment. Sound engineering practice and often regulations mandate that instrumentation meet guidelines and have agency approvals for installation zone safety. Depending on actual installation location, at a minimum the environment will require Class I, Division II and often a more rigorous Class I, Division I [Zone 1 II2GD Ex d IIC] approvals. FCI Model ST51 meets all of these and has obtained the global agency approvals that ensure your installation is always safe and complies with regulations. And, unlike manufacturers who merely provide their transmitter electronics in an approved OEM enclosure, FCI submits its entire instrument to agency testing. FCI product approvals are different because they are comprehensive system approvals that also take into account the sensor and seal requirements as well the “T” (temperature) ratings. FCI agency approvals are on the total instrument. With ST51 you are assured of the integrity of total instrument approvals that meet or exceed safe engineering practice for your applications.
