Product Details
1、 Product Overview
The DK800 glass rotor flowmeter is a process detection instrument designed specifically for measuring small flow rates of single-phase non pulsating fluids (liquids or gases) in closed pipelines. It adopts a vertically installed glass cone tube and float structure design, supporting high-precision flow monitoring and real-time adjustment. Suitable for precision flow control and process optimization in fields such as chemical, medical, environmental protection, food and light industry.

3、 Product Features
High precision measurement.
Corrosion resistant design,Adopting a 304 stainless steel base, fluoroplastic and fluororubber seal, it can withstand strong acids, strong alkalis and organic solvents.
Transparent visible structure,Hard glass cone tube with spherical/conical float, real-time observation of flow status, intuitive reading.
Flexible adaptability.
Supports panel installation, quick connectors, and sleeve connections, compatible with various piping systems.
4、 Application scenarios
1. Medical equipment: Micro flow calibration of infusion pumps, ventilators, and other instruments.
2. Chemical analysis: Fluid control and monitoring of chromatography and reaction vessels.
3. Environmental monitoring: Gas flow detection and water quality analysis in waste gas treatment.
4. Food and light industry: precise control of beverage filling and trace addition of chemical raw materials.
5、 Installation and maintenance
1. Installation requirements
It must be installed vertically (with the big end of the cone facing upwards), and the pipeline needs to be flushed clean to avoid blockage by impurities.Reserve 5-10 times the diameter of the straight pipe section upstream and at least 250mm of straight pipe section downstream.
2. Operating standards
Open the upstream valve to full open, then slowly adjust the downstream valve to control the flow rate, and sequentially close it when stopping.
3. Maintenance suggestions
Regularly clean the cone tube and float to prevent dirt from affecting accuracy; If the float is stuck, it needs to be disassembled and cleaned.After long-term use, recalibration is required, and the indication value needs to be corrected when the medium density or temperature changes.
