DescriptionPortable calibration units of the SPU-3M-100 series (with a tablet) are designed for checking household gas metering devices of standard sizes G1.6-G65 at the place of operation without dismantling. The installation has inherited all the technical solutions and advantages of the junior SPU-3 line, but at the same time it is distinguished by an extended upper limit of the flow range of the measured medium: from 0.1 to 100 m3/h. This modification of the installation allows the verification of household metering devices of standard sizes up to and including G65. The verification of gas meters (flowmeters) is based on the comparison of the results of simultaneous measurements of the volume (flow rate) of the working medium flow by the meter being verified and the installation connected sequentially to the measuring line. features: • Verification of counters of standard size up to and including G65; • The compactness of the installation within one portable case is preserved; • Fully automated verification procedure; • Dynamic range 1:1000; • Autonomous operation from the built-in power supply up to 10h; • Built-in printer that allows you to print the verification protocol on the spot; • The installation software allows you to keep an archive of verifications; • Uploading data to a PC via a USB connector. GENERAL CHARACTERISTICS: The range of reproducible test flow rates is from 0.1 to 100 m3/h. The limits of the permissible relative error of the installation when measuring the volume of gas under operating conditions are ± 0.4%. The limits of the permissible relative error of the installation when measuring the volume of gas reduced to standard conditions are ± 0.5%. The limits of the permissible absolute error when measuring temperature are ± 0.15 ° C. The limits of the permissible reduced error when measuring excess (absolute) pressure are ± 0.15%. The excess pressure of the measured medium in the pipeline is 50 (300) Kpa. Battery life from an internal power supply, at least – 10 hours. The weight of the installation is 20 kg. Overall dimensions - 500x600x180 mm. Average time to failure, at least – 12,000 hours. Average service life, at least – 12 years.
