In early May 2019, our company received a call from a petrochemical enterprise in Liaoning, who wanted to purchase a batch of flow meters. Our technical personnel immediately contacted the customer's on-site technical personnel to understand the working conditions and conduct technical exchanges. Based on our understanding, our technical personnel informed our sales team of the specific situation, and we compiled a detailed model parameter quotation table and sent it to the customer. The customer later made multiple adjustments and finally confirmed the plan. In the process of communicating with the customer, they recognized our technology and felt that we were a trustworthy enterprise. In terms of business negotiations, due to the large quantity of customer demand, we also offered a discounted price, and finally confirmed the purchase contract at the end of May. 70 turbine flow meters have been processed and packed, waiting for shipment. We will introduce pictures of the on-site installation to everyone later.
