Introduction
Shenitech offers state-of-the-art ultrasonic products for accurate and reliable flow measurements. Powered by advanced
signal processing and electronics technologies, as well as proprietary technologies on ultrasonic transmission/receiving and
automatic signal quality tracking, the Shenitech STUF-xxx and STxxx series flowmeters can achieve high accuracy (better
than 1%), high linearity (0.5%) and high repeatability (0.2%). They can adapt to diverse pipe materials and fluid
conditions automatically. While they are most suited for clean liquids, they can also work reliably with liquids that have
solids content as much as 5%.
Shenitech has designed a wide variety of products to meet the demanding requirements of today’s versatile applications.
For portable applications, we have a handheld flowmeter that is light-weight, compact and very easy to install/uninstall.
For non-intrusive applications (high-pressure pipes, hygienic processes, chemicals, food, etc), we offer non-intrusive
flowmeters with transducers that can be clamped onto the outside of the pipe and have absolutely no contact with the
liquids inside. For applications that require best accuracy, long-term stability and low maintenance, our insertion type and
flow-cell type flowemters are the best choice. For cost-sensitive, large-volume applications, such as steel plants that need
to have many flowmeters installed and networked, our low-cost ST301 series would be the best product.
In today’s energy-sensitive economy, energy consumption metering has become very important. Shenitech has developed
ultrasonic heat meters (BTU), non-intrusive thermal energy measurement systems as well as Automatic Meter Reading
(AMR) systems to meet these urgent needs. Compared with traditional BTU meters, our products do not have moving
parts, and thus need no maintenance and last much longer.
The list of applications of the Shenitech products is constantly expanding. In brief, wherever you have an application, we
can provide you with a solution.

STUF-300F Wall-mount Ultrasonic Flowmeter
The STUF-300F series products are high-performance, NIST-standard compliant, wall-mount ultrasonic
flowmeters. They are normally installed in fixed locations for long-term flow measurement. There are three
categories in this product family:
STUF-300FxB: non-intrusive clamp-on flowmeter
STUF-300FxC: zero-maintenance insertion flowmeter
STUF-300FxG: plug & play high-accuracy flow-cell flowmeter
The main differences among the three types of flowmeters are their transducers. Their base units (electronics
consoles) are the same. The model number of the base unit is STUF-300F.
To accommodate different applications, the base unit STUF-300Fx also comes with four variations:
Standard base unit STUF-300F1, enclosure-enhanced base unit STUF-300F2, IP67-enclosure base unit
STUF-300F3 and GSM/GPRS wireless-enabled base unit STUF-300Fn.
Standard
(STUF-300F1)
Wireless-enabled
(STUF-300Fn)
All of the four base unit versions are based on the transit-time technology for high accuracy flow measurement.
They usually work best with clean liquids. However, with our proprietary digital signal processing algorithms and
automatic signal quality tracking functions, they can also work with liquids that have particle contents up to 5% in
volume, and even up to 10% if the particle size is less than 50um. The base units also provide networking
capabilities, analog input, analog output, digital output, etc. They can also be expanded to conduct thermal energy
measurement.
The wall-mount ultrasonic flowmeters are generally used for liquid process control, continuous flow monitoring and
any application where long-term flow measurements are needed. Examples of applicable liquids include: water (hot
water, chilled water, city water, sea water, etc.); sewage, waste water; oil (crude oil, lubricating oil, diesel oil, fuel
oil, etc.); chemicals (alcohol, acids, etc.); solvents; beverages and liquid food, etc.
In the following, we will use the standard version, STUF300F1, as an example wiring diagram. For other base unit
versions, please contact Shenitech for availability.

STUF-300Fn Wireless Ultrasonic Flowmeter
The base unit of the wall-mount ultrasonic flowmeter, STUF-300F, can be equipped with a GSM modem or a
GPRS modem. The GSM/GPRS-enabled base unit, namely STUF -300Fn, can be used to measure liquid flow
wirelessly. It can also be easily networked to form a wireless flow monitoring s ystem.
Depending on the transducer used, the STUF-300Fn base unit can be used to comp ose a wireless clamp-on
flowmeter (STUF-300FnB), a wireless insertion flowmeter (STUF-300FnC) or a wireless flow-cell flowmeter
(STUF-300FnG).
• When the flowmeter is equipped with a GSM modem, you may use your cell phone to check the flowmeter
reading and flowmeter working status anywhere and anytime
• When the flowmeter is equipped with a GPRS modem, you ma y use your computer to program the
flowmeter, monitor the flowmeter status and read flow data continuously from a remote location. The data
can then be recorded into your database
• Shenitech provides the PC software for flow monitoring system management. Please contact

STUF-300R1 Thermal Energy Meter
The STUF-300R1 thermal energy meter is used to measure the energy
transfer/consumption of a liquid-based energy production or delivery system.
It is consisted of a wall-mount ultrasonic flowmeter and a pair of PT100
temperature sensors (one for supply and the other for return).
The thermal energy consumption Qt is calculated as follows:
Qt = Q x (T2 – T1) x Ct
or
Qt = Q x (TC2 – TC1),
where Q is the flow rate measured by the flowmeter, and T1 and T2 are the
temperature measured by the two PT100 sensors at the supply and return
points, respectively. Ct is the specific heat (or the thermal capacity
coefficient) of the fluid. TC1 and TC2 are the thermal capacities
corresponding to the T1 and T2 temperature.
The flowmeter part of the thermal energy meter is similar to the STUF-300F1x
high-performance ultrasonic flowmeter described in the previous pages. As
there are three kinds of ultrasonic transducers, there are three types
of thermal energy meters as well: STUF-300R1B for the clamp-on
type, STUF-300R1C for the insertion type and STUF-300R1G for
the flow-cell type.
The PT100 sensor is a standard 3-wire RTD temperature sensor. It
comes with two varieties: the surface-mounting type and the
insertion-mounting type (see flowing figures). The left is easy to
install while the right has better accuracy. With temperature
calibration, the STUF-300R1 is able to provide 0.1°C accuracy over
a wide temperature range (-40°C~155°C.)
Note: you ma y use your own temperature sensors. Please specify
that clearly when placing the order.

STUF-280W Ultrasonic Water Meter
The STUF-280W water meter is similar to the STUF-280T heat meter. The only difference is that STUF-280T has RTD temperature
sensors and STUF-280W does not. Therefore, please refer to the previous pages for the
specifications.
Model Number:
STUF-280W-DNx-y-z or STUF-280W-INx-y-z
where x is the pipe size in mm, y is the output option (0: pulse, 1: M-Bus, 2: RS485), z is the
pipe joint option (0: BSP, 1: NPT, 2: Metric Flange, 3: ANSI Flange).
Example 1: STUF-280W-DN25-0-0 stands for the STUF-280W water meter for pipe
DN25mm with pulse, BSP joint. Example 2: STUF-280W-IN1-1-1 stands for the STUF280W water meter for pipe 1” with M-Bus, NPT joint. Example 3: STUF-280W-DN100-1-2
stands for the STUF-280W water meter for pipe DN100 with M-Bus and metric flange joint.
Automatic Meter Reading (AMR) System
A t ypical automatic meter reading system (AMR) is
consisted of a number of STUF-280T/W heat/water
meters and one or several M-BUS concentrators (BACnet
bus not explained here.) Each concentrator can be
connected to a data center computer directly or through a
GPRS transceiver wirelessly.
STUF-280T/W uses M-BUS to communicate with the
concentrator. M-BUS simply uses two non-polarized
wires to achieve a variety of options for reliable meter
reading, remote diagnosis, remote control, incremental
pricing, time-based pricing, batch service, prepaid
billing, etc. This BUS system is also simple and
economical to wire and construct.
Based on many years’ meter reading experience, we
have established a hierarchical heat management
system architecture that is flexible, scalable, reliable
and robust. This architecture has been fully
implemented in our Data Center Manager software.
There are four layers in this software topology. The
top layer is for the DTU management, upper middle
layer for the area management, lower middle layer for
the building management, and bottom layer for the
client management. A DTU region could have several
Areas, an Area could have many buildings, and a
building could have many clients.
