• This listing is for DN15-6000mm pipe size, the water temperature is from 0-160c
  • It comes with S1H transdcuer (DN15-100mm) and NEW M1H transducer (DN50-700mm); 5m*2 signal cable;metal clamp fixture; one aluminium case; tape ruler;adaptor; data line
  • You must use coupling agent when you measure the flow rate. If you do not use the silica gel, it will have no signal

It comes with factory issued calibration certificate



Typical Applications 


The STY404 flow meter can be virtually applied to a wide range of measurements. The measured pipe ranges 20-6000 mm [0.5 - 200 inch]. A variety of liquid applications can be accommodated: ultra-pure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc.   Because the instrument and transducers are non-contacting and have no moving parts, the flow meter can not be affected by system pressure, fouling or wear. Standard transducers are rated to 110 ºC.   Higher temperatures can be accommodated. For further information, please consult the manufacturer for assistance. 


Data Integrity and Built-in Time-Keeper 


All user-inputted configuration values are retained in the built-in non-volatile flash memory that can store them for over 10 years, even if power is lost or turned off. Password protection is provided to avoid inadvertent configuration changes or totalizer resets.  A time-keeper is integrated in the flow meter for the index of date totalizing and works as the time base of flow accumulation. It keeps operating as longas the battery’s terminal voltage is over 1.5V.  In case of battery failure, the time-keeper will not keep running and it will lose proper time values. The user must re-enter proper time values in case the battery becomes totally exhausted. An improper time value affects no other functions but the date totalizer.
