Water company usersCompared to traditional mechanical meters, the YST306D50-BF223 equipment from Dalian Yister requires almost no maintenance in the municipal pipeline network. Previously, mechanical meters had to be dismantled and cleaned every six months due to sediment blockage. Now, they only need to be inspected once a year, and the low flow monitoring effect is good. It helped us discover three small leaks in the pipeline network, reducing water resource waste; ”

Thermal heating enterprisesAfter using Dalian Yister's products for household metering, user satisfaction has increased. This is because the metering data is transparent, supports mobile phone usage queries, and has a wide range of measurements. Even if the user's home heating is turned down, accurate metering can still be performed, reducing usage disputes

Sewage treatment plant usersThe heat measurement of the sludge drying system used a mechanical meter before, but it got stuck due to sludge impurities in less than a year. After replacing it with the YST306D50-BF223 model from Dalian Yister, it has been used for 3 years without any problems. Moreover, the data can be connected to the central control system in the factory, which facilitates real-time adjustment of the drying process and reduces energy consumption; ”

Hospital Logistics DepartmentThe disinfection of hospital wastewater requires high temperature. Dalian Yister's products not only have accurate measurement, but also are resistant to wastewater corrosion. Previously, the meter used had to be replaced every six months due to sensor corrosion, but now this one has been stable for two years, reducing maintenance costs

Project BackgroundIn winter, the temperature in a northern city is low (-10 ℃ to -20 ℃), and the municipal secondary water supply pipeline is prone to freezing. Therefore, it is necessary to use hot water circulation for insulation. Previously, heat was estimated based on time, which resulted in significant energy waste;

Project BackgroundThe wastewater from the chemical plant contains acidic substances (pH value 2-3), and the pretreatment stage needs to be heated to 60 ℃ to promote the reaction. Previously, a mechanical heat meter was used, but due to corrosion and impurity blockage in the wastewater, the measurement deviation reached more than 20%, and it needs to be dismantled, cleaned, and maintained every month;

Application requirementsThe product needs to be corrosion-resistant, anti clogging, and accurately measure the heat generated during the pre-treatment process; Data access to the energy management system of the chemical plant for cost accounting purposes;

Project BackgroundA centralized water supply project in a rural area in the south covers 10 natural villages, and the temperature occasionally drops below 0 ℃ in winter.
