Key Features of the Device:

1. Bi-directional data transmission enables unmanned control operation.
2. Integration of metering, automatic control, and fuzzy control functionalities.
3. Supports auto-calibration and data storage capabilities.
4. Built to withstand high temperatures, corrosion-resistant, and anti-scaling. Critical components are fabricated from stainless steel and alloy materials, with additional material tempering for enhanced properties.
5. Employs aerospace flow measurement technology, offering a wide range ratio, high precision, and extended service life.
6. Accommodates both wired and wireless (expandable based on customer requirements) dual communication interfaces, catering to diverse client needs.
7. Incorporates magnetically balanced Hall effect sensors, ensuring high valve control precision, rapid dynamic response, and consistent performance stability.

This device has resolved several key issues for our clients:

1. **Accurate Water Injection in Oilfields:** It tackles the prevalent problem of internal leakage or inability to achieve precise control under well pressures exceeding 30MPa, which hampers the objective of constant pressure and stable flow water injection in oilfields.

2. **Management of Water Injection Equipment:** It enables bidirectional transmission of water injection data, allowing operators to manage water injection tasks remotely from the station, thereby facilitating unmanned operation in pure water injection sites.

**Customer Approval:**

By the end of 2016, over 600 sets of our flow measurement and control devices were installed in water injection stations and water distribution valve groups across the eastern oilfields of Shengli Oilfield. These installations effectively addressed the challenge of high-pressure differentials and low-flow measurement, leading to a substantial overall improvement that garnered positive feedback from clients.

**Recognition and Expansion:**

Sinopec Zhongyuan Oilfield dispatched a specialized expert team to visit Shengli Oilfield for observation and learning, followed by an inspection of our company. This engagement resulted in a supply agreement being signed that year, initiating their first purchase of 50 units from us.

Due to the success of this product, our company was honored as an "Outstanding Enterprise in Technological Innovation" by the Xi'an Economic and Technological Development Zone in early 2017.
