Dear family members of Duoqin Instrument:
According to national arrangements, the Labor Day holiday in 2025 will be from May 1st (Thursday) to May 5th (Monday), with a total of 5 days of compensatory leave. I will be working on Sunday, April 27th.

In order to facilitate family members to enjoy the holiday, the company has decided after research to adjust the holiday time for Labor Day in 2025 to April 30th at 11:30 and May 6th at normal work. We hope that all family members can inform each other and pay attention to safety when going out for sightseeing.
Free highway access on May Day, 2025:
According to the Implementation Plan for Exemption of Small Bus Toll on Major Holidays issued by the state, the time range for free high-speed travel is four national statutory holidays including Spring Festival, Qingming Festival, Labor Day, and National Day. The free period starts from the early morning of the first day of the holiday and ends at 24:00 on the last day of the holiday.
Ordinary toll roads are based on the time when vehicles pass through the toll lane at the toll station, while highways are based on the time when vehicles leave the exit toll lane. The free range of vehicles is for small passenger cars with 7 seats or less.
The technical service team of Duoqin Instrument has been focusing on flow meters for nearly 20 years. We highly recommend various flow meters such as vortex flow meters, electromagnetic flow meters, steam flow meters, gas flow meters, elliptical gear flow meters, metal tube float flow meters, ultrasonic flow meters, etc., especially for flow GPRS mobile and PC data online monitoring and other technical services.
