1. Product Overview：
A digital turbine flow meter is a velocity flow meter used to measure the volumetric flow of low viscosity, uniform liquids flowing continuously through closed pipes. The sensor outputs a signal proportional to the liquid volume and is divided into current display type and pulse output type. The pulse type is used in conjunction with the corresponding flow totalizer or control equipment, and can be used to measure the instantaneous flow and accumulation of liquids. Flow and control. Liquid turbine instruments can measure water, high water content crude oil, oily sewage, diesel, gasoline, light oil, beer, beverage milk and other video-grade liquids. It has the characteristics of high precision, easy maintenance, simple installation and low cost of use. According to user needs, multiple output modes can be customized to achieve different functions: standard current output, pulse output, standard analog current output, fluid cumulative flow display, instantaneous flow display, etc.

2. Working principle and scope of application:
Digital turbine flow meter is a device widely used in industrial processes to accurately measure liquid flow. It is used to measure the volume of liquid passing through a device over a specific period of time. The flow meter consists of an impeller, and the rotation speed of the impeller is proportional to the flow rate of the fluid. The number of revolutions of the turbine is counted by a digital sensor connected to an electronic output device to display the measurement reading.
This type of meter measurements are very accurate, reliable, and have fast response times. It provides precise results even when used with highly viscous fluids or liquids containing suspended particles. And it is easy to install and does not require daily maintenance.
The equipment has become an integral part of many industries, including chemical, petroleum, food processing and water treatment plants. It helps optimize production processes, control fluid flow and monitor resource usage. It is a cost-effective solution that increases efficiency, reduces production costs and improves overall output quality.
In conclusion, liquid turbine flowmeters are a valuable investment for manufacturing industries. It provides accurate, real-time data that helps enhance workplace safety, reduce downtime and save costs.
