Listed below is a a small sampling of some of the manufacturers we complete flow calibration's with on a regular basis. In the piston or bell prover flow meter calibration procedure, a known volume of fluid is forced through a flow meter under test. Graftel's labs have worked with hundreds of name brand and sometimes not-so-name brand flow meters and gauges, we specialize in working with you to keep your valuable equipment calibrated. The calibration flow laboratory is always maintained at controlled ambient conditions such as temperature, humidity for master flow meters’ best performance. ![]() Listed below is a small sampling of the types of equipment we can perform flow calibrations on in our labs. A NIST traceable and ISO 17025 accredited certificate.Air & GAS FLOW METER CALIBRATION SERVICES INCLUDE:Īll flow calibrations completed by Graftel come with: Graftel can also perform these calibrations at your site. Air or gas or mixture of gasses may be used. Our highly trained technicians can perform. ![]() This is a simple process often referred to as the bucket and stopwatch method. We also Offer a complete line of flow and testing equipment. The flowmeter calibration procedure involves the diversion of the fluid onto a mass comparator over a given timescale, where the basic mass flow rate measurement is derived by mass over time calculation. We have an accredited ISO-17025 in-house 700 GPM liquid and 18,000 LPM gas flow meter calibration lab. Each system can achieve uncertainties up to 0.15% of reading. Graftel offers a personalized and professional team for your flow meter calibration needs. Flow rates between 1sccm up to 25,451 slm are measured. Graftel maintains five NIST traceable primary air flow calibration systems. Air & Gas Flow Calibration Services By Graftel ISO 17025 Certified ![]()
