            Feature:     The latest & most advanced is “Ultrasonic.” The major advantages of Ultrasonic over other methods of flow measurement is as below
1)Highly accurate.
2)Tamperproof
3)Liquid need not be conductive.
    4)Can be fitted in complicated pipe lines since flow path straightening requirement is minimal.
5)Availability from DN15mm to 6000 mm.
6)Choice of battery powered or DC or AC powered.   7)Fastest & simplest installation & can have choice of installation without shutdown of line supply.
8)Negligible installation cost.
9) One unit can measure flow in different diameter sizes.            More detailes of the  ultrasonic flow meter(TDS-100F), welcome to our website www.tds200.cn
