BTU meters are used on chiller lines to measure the energy consumed by the chillers in the cooling process. Our BTU meters are constantly used in projects and recommended by various consultants and BMS providers across the country. Shenitech ST-280T BTU meters are based on Ultrasonic Transit Time Technology. These BTU meters assure Class-2 accuracy and have a tamper-proof model as per the energy norms in various countries.

These BTU meters have an in-built battery i.e. no hassles of power supply on the site. Battery back-up lasts for 6 years. Since there is no moving part in the sensor assembly these meters are maintenance free and hence has high reliability.

Unmatched Advatages of Shenitech BTU meters

• We have an entire range of ultrasonic flowmeter from 15mm to Line sizes more than 700mm and customized for higher line sizes as per your requirements.
• Our meters can detect a very high capacity of flow. Because of the high flow capacity, we need a lower size meter for a certain flow rate. - For example: 100mm line size might require our 65mm flow meter.
• This enables cost saving and also proper sizing of the meter.
• All our meters are wet calibrated where the temperature and flow sensor are calibrated together and we give a calibration certificate with each and every meter.
• All our meters have an inbuilt battery backup – guaranteed for a minimum of 6 years.Hence no hassels of giving rthe power supply and spending unnecessary cabling and cable laying cost.
• No reflector used for detection of flow. This ensure that meters are very robust and don’t have any problems even after years of operation. This ensures efficiency of meter and maintenance free years of operation.
• Single point source for meters, hardware for interconnectivity (M-Bus) and software for billing and meter reading. This ensures zero dependence on a third party. Also we ensure that the system is up and running at all times.
• Tamper proof design---ensures no tampering in the final bill 2 years international warranty on all the products

Details :

• 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”)

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.

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.

Details :

• 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”)

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.

• Non-intrusive thermal energy/BTU measurement
• Easy and economical installation; no pipe work required
• No moving parts to wear and tear; no maintenance required
• Industrial grade temperature sensors and ultrasonic sensors for improved robustness
• Paired PT100 RTD sensors and ultrasonic transducers for improved accuracy
• Suitable for pure liquids and liquids with some particles; no dependency on conductivity

Conclusions :

• The entire installation and system tuning was completed within two days time, therefore a quick andeconomical installation. This is only possible with non-intrusive clamp-on ultrasonic technology. The fact that the size of the pipe was as large as 24 , one can only imagine how expensive and labor intensive it would have been to use another type of technology, i.e., mechanical flowmeter or magnetic flowmeter. STUF 300R BTU meter resulted with saving the customer major installation costs and quickly delivered most favorable results.
• In summary, the benefits of the Shenitech Metering STUF 300R energy metering system include:
• Non-intrusive installation thereby significantly saving money and time, in particular for large size pipes No moving parts, thus, almost no maintenance, thereby savingmaintenance costs Accurate flow and BTU measurement improves chiller plant control Real-time data and balancing information to improve system efficiency Continuous monitoring of flow, temperature, and energy transportation guarantees system performance along with providing alarm for potential risk or energy leakage
