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

 Q=v*A 

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.

BTU Meter


Clamp-on Ultrasonic BTU Meters

The STUF 300R ultrasonic thermal energy meter provides abundant capabilities for accurate thermal energy measurement of a liquid-based thermal energy production / transferring system. It is the 3rd generation energy meter from Shenitech. Compared to its predecessors, the 3rd generation offers better performance and a richer feature set, all at a lower price.
The STUF 300R system is consisted of a high performance ultrasonic flowmeter EF10 and a pair of standard PT100 temperature sensors. The ultrasonic flowmeter is based on our cutting-edge clamp-on flow measurement technology, which is capable of measuring the flow from outside of a pipe accurately and reliably. Due to the non-intrusive nature of this technology, there is no pipe cutting, no moving parts, no pressure drop, no leaks and no risk of contamination. Besides, the installation is simple and requires no special skills or tools.
The two PT100 sensors, which could be either insertion type or surface-mounting type, are used to measure the temperature of the supply flow and the return flow. The energy consumption rate is then calculated based on the temperature difference and the measured flowrate. A built-in energy totalizer is used to accumulate the amount of energy delivered.
STUF 300R provides versatile input/output interfaces, such as isolated digital outputs, relay output, batch control, alarm, 4-20mA output. In addition, the built-in isolated RS-485 port with surge protection and MODBUS support makes remote energy monitoring and energy meter networking easy and reliable. Other output modules, such as BACnet module, Ethernet module, GSM/GPRS wireless module, RF module and more, can be added to the standard package.
STUF 300R is an ideal choice for improving HVAC, energy production and building energy efficiency in terms of heating, cooling ventilation and air-conditioning.

Variable Air Volume Boxes (VAV Boxes)



Variable Air Volume (VAV) Boxes are required to control air supply as per the requirement in an air distribution network of air flow in a particular zone. VAV Boxes are used very frequently in office space, commercial towers, conference rooms & control area to control temperature & try to achieve a particular set point given to its thermostat.
VAV Boxes by varying airflow can control various parameters like temperature, CO2 level, positive differential pressure, depending upon its application. It also attains substantial energy saving by blocking access air into the duct & hence in-turn low rpms of AHU fans, unlike constant air volume system which is not capable of achieving high energy efficiency.
NinthWave   is associated with Honeywell Automation to bring out the best quality Variable Air Volume system to its customers. WE became proud ‘exclusive channel partners for VAV system’ of Honeywell Automation for complete country in year 2014.
We provide Pressure Independent type Variable air volume boxes, factory fitted with a microprocessor DDC controller, damper, damper actuator, cross flow velocity sensor with differential pressure transmitter, thermostat and in-built step down transformer. VAV boxes are calibrated in factory & undergo Honeywell’s stringent quality check tests before being shipped out of factory.
We can also customize VAV boxes as per the requirement of customer like, single skinned, double skinned, by-pass, multi leaf, with heating element etc.

VAV controller comes with BACNet® MS/TP communication standard, which is widely accepted for third party integration across the country. We also provide tested integrators for VAV integration.
In past years we have successfully commissioned VAV system at so many prestigious multi-national client offices across the country, catering to their customized requirements.
Applications successfully commissioned are briefed below.
Zone Temperature Application This is the most common type of application, required to control temperature by varying air flow. The most critical of them were heating & cooling application, where air temperature changes as per the weather condition, & hence VAV operation also reversed to achieve a set point. Our technical team has mastered these applications to ensure proper operation of the system.
Fresh Air/ Ventilation (Demand Control Ventilation) Application In Demand Control Ventilation, a VAV operates to limit & measure the air flow required to maintain a CO2 differential level in a particular zone. A high CO2 level can cause lower work efficiency of the work force. Also access fresh air intake in an AHU can decrease its energy efficiency. In order to control an optimum level of CO2 differential level, a Variable Air Volume Box finds its application, it measures CO2 level & modulate accordingly to maintain a CO2 level inside a work space. We have commissioned systems having such requirement across the country successfully.
Our controllers are fully compatible to maintain VOC level, rH level etc. to provide a controlled environment.
Differential Pressure Application
We have also come across differential pressure application, where a VAV is placed in return duct, & it allows maintaining a higher pressure in the controlled area. This application is generally used in controlled environment like clean room, drug formulation chambers, storage cabins, Server rooms etc. Applying VAV system, an efficient dust free system can be provided by maintaining a positive pressure inside the zone.
We have undertaken these critical application & successfully commissioned them.
