Technology Leader and Total Integrated Solution Provider
Ultrasonic Flow Meter
Ultrasonic flow measurement is among the best & most accurate technology available these days. It is widely accepted & prominently used across the industries due to its non-cohesive nature with the flow media. It is also non-effected in high magnetic field zones, where other technologies like electromagnetic & Boltzmann’s turbine technologies might have a challenge.

Our Shenitech ultrasonic flow meters work on Transit time principle which ensures high accuracy. Our ultrasonic flow meters  are   used  not  only  for  domestic
water application but also in dirty water having high TDS, in Sewerage treatment & effluent treatment application.
Transit time principle is annotated as below.
“It is the time difference taken by two UH frequency pulses to reach the diametrically opposite ends of the pipe, which is related to the velocity of the fluid media inside pipe in direct proportion”

Suppose ‘T1’ is the time taken by pulse to travel downstream to the flow of media & ‘T2’ is the time take by the pulse to travel upstream of the flow media moving unidirectional with velocity ‘v’ , then time difference ‘δT’ is related to velocity as
(T2 – T1) = δT      Or      δT α v      Or      δT = k * v      Or      δT/k = v
Cross section area of pipe is ‘A’
Then Flow rate ‘Q’ can be calculated as
We can offer inline type as well as clamp-on and insertion type sensors, depending upon the applications’ requirement. Our flow meters offer all standard signal outputs like analog outputs (4- 20 mA or 0-10 VDC), Modbus over RS-485, M-Bus etc. which is widely accepted for third party integration.
Benefits & Features:
Low maintenance as no moving parts
High Accuracy as high as ± 1%
OIML R49 standard. CE Approval
Low pressure drop
Tamper Proof Design
Low Cost Over long run
We have all types of sensors option available as far as mounting is considered. The sensor selection is generally depend upon the application & site conditions. We recommend to take our expert advice before making selection of appropriate sensor.
Clamp-on Flow meter
Non-intrusive. No risk of contamination or leakage
Easy installation. No pipe cutting, no hole drilling. Save installation cost
Can be easily moved from one location to another
For pipe size DN25 ~ DN6,000 (1”~240”)
Insertion Flow meter
Excellent long-term stability
Better accuracy than clamp-on
Better signal strength, thus, better performance than clamp-on when liquid has some solids
For pipe size ≥DN80 (3”)
Inline Flow meter
Excellent long-term stability
Best accuracy among the three transducer types
Flowmeter is pre-programmed in factory, thus, it is a simple plug and play device
For pipe size DN10~DN500 (3/8”~20”)
