How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Testing process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
This standard specifies the terminology, classification, technical requirements, test methods, and inspection rules of the differential pressure indicating averaging tube flowmeter (hereinafter referred to as the flowmeter) for water quantity measurement. The flow meter is composed of sensors. The water column differential pressure gauge consists of two parts. This standard is applicable to the measurement of water in the tap water industry. 2. Reference standard GB/T 13983 Basic Terminology of Instruments and Meters ZBN10 002 Flow Measurement and Instrument Terminology ZBN10006 Rules for the Preparation of Industrial Automation Instrument Product Models ZB Y0O2 Instrument Transportation, Storage, Basic Environmental Conditions and Test Methods ZB Y003 Instrument Packaging General Technical Conditions 3 Terminology In addition to the terms specified in ZB N10 002 and ZB Y247, the following terms are also used in this standard. 3.1 Nominal pressure is the maximum allowable pressure that ensures the normal operation of the flow meter. 3.2 Flow velocity range: The range limited by * high flow velocity and * low flow velocity. 4. Classification 4.1. Model preparation should comply with the provisions of ZB N10 006. 4.1.1 The cross-sectional shapes of sensors (detection rods) include diamond, circular, oblate, etc. 4.1.2 The opening methods for the detection rod include equal area method, equal flow method, linear logarithmic method, Chebyshev integration method, and Gaussian method. 4.1.3 The sensor of the flow meter can be installed horizontally or vertically (or obliquely) on the corresponding pipeline with the same nominal diameter as the upstream and downstream. The installation is an open hole plug-in type. The installation requirements can be found in Appendix A.4.2 Basic Parameters 4.2.1 Accuracy The accuracy level of the flow meter is divided into 1.0.1.5 and 2.5 levels. 4.2.2 Nominal diameter
