Thiết bị sử dụng trong kiểm soát quá trình ở các nhà máy thực phẩm, đồ uống, hóa chất hay xử lý nước để kiểm soát nồng độ môi chất lỏng. Thiết bị có thiết kế nhỏ gọn, hoạt động ổn định và cho kết quả nhanh chóng có thể thay thế cho phương pháp kiểm tra, phân tích trong phòng thí nghiệm. Điều này giúp cho việc kiểm soát nồng độ chất lỏng được kịp thời, tiết kiệm và hoàn toàn tự động (có thể xuất tín hiệu điều khiển quá trình).
Density and concentration measurement system.
- Maintenance-free, no moving parts
- Pump protection can be provided with the same process connection
- ATEX certification
- EHEDG and 3-A approvals
Dosing preliminary, interim and final products; determining exact density or concentration; monitoring quality and controlling processes: all these activities rely on accurate and reliable density measurement. Endress+Hauser’s Liquiphant M density system offers outstanding product quality data, helping you to streamline your process, improve yield and save money!
Endress+Hauser makes use of the tried and trusted vibronic principle to provide reliable data on density and quality just as reliable as it does level limits. As soon as the density or the concentration of the medium changes, the resonant frequency changes too. The tines of Liquiphant sense this change in frequency and the FML621 density calculator displays this information in measurements you understand, be it °Brix, °Baume or indeed any units specific to your application.
In the chemical and food & beverage industries, concentration is an important process variable. In order to determine concentration levels, extensive offline procedures and expensive laboratory analysis are often required. Liquiphant M, in combination with a temperature probe and FML621 density controller offers a cost- effective alternative. They provide reliable online density measurement at a glance, increasing plant availability, improving process control and reducing product wastage.
More than just a density controller The Liquiphant M density measurement system can be used across the process industries for concentration measurement, quality statements and purity indications or even as a basic variable in calculations and simulations. What’s more, Liquiphant M can simultaneously provide dry-run protection and can be combined with other measuring instruments (e.g. flowmeters or radar devices) to provide additional values such as mass or mass flow information.
Application
*Pressure and temperature information required depending on the application.
- Liquiphant M sensor with electronic insert FEL50D (pulse output)
- Temperature sensor (e.g. 4…20mA output)
- Pressure transmitter (4…20mA output)
- Liquiphant density and concentration computer FML621 with display and operating unit
Please note
- Measurement can be affected by:
- Air bubbles at the sensor
- Unit not fully covered by medium
- Solid media build-up on sensor
- High fluid velocity in pipes
