Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of online instruments, it is recommended to prioritize checking key technical parameters such as measurement range, accuracy level, and signal output method. For example, chemical process monitoring typically requires a 0.5 level accuracy and 4-20mA analog output.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. These suppliers are more reliable in scenarios such as sewage treatment and energy monitoring.
  • Different application scenarios have differentiated requirements for the protection level of online instruments. For example, the food industry requires protection of IP67 or above, while the metallurgical industry needs to consider the selection of high-temperature resistant materials.
  • When evaluating online instrument suppliers, it is recommended to compare them horizontally based on their industry data support capabilities. For example, practical application cases of flow meter suppliers in the oil pipeline field can serve as effective reference.
