Enhanced Durability! Lnnovative water meter for the new-era

As consumption of water has increased in the recent years, an advanced water meter has been desired for the use of long time and stable high accuracy measurement with trouble-free operation. Responding to these needs, Aichi has conducted proprietary research over and over and has succeeded in developing the world′s first electromagnetic water meter “SU Series” and “SY Series” that provides 8 years of non-stop service with built-in battery. These water meters for the new-era are suitable for water control with innovative enhanced durability that expands the world of measurement.

Outstanding features that expand the world of measurement

Outstanding durability with no moving parts

Since there are no rotating or sliding parts such as vane wheel or indication gears, troubles caused by wear of moving parts and intrusion of foreign substances are eliminated. Therefore, stable measuring accuracy can be maintained over a long period of time.

High accuracy measurement whether large continuous or small flowrates

The SU Series has almost no head pressure loss at maximum flowrate measurement, it is suitable for measuring flowrates of large continuous water supply and distribution. The SY Series is capable of measuring small flowrates with high accuracy owing to its special structure.

Wider measurement range

The measurement range is as wide as 1:200 for the SU Series, and 1:1000 for the SY Series. High-accurate measurement from very small (min. accurate flowrate) to large (max. flowrate) flowrates is possible.

8 years of continuous operation with a built-in battery

The power consumption has been reduced to 1/1000 (according to Aichi’s comparison data) from the conventional general electromagnetic flowmeter, and with a built-in lithium battery applied, 8 years of continuous measurement is realized. Consequently, there is no need of maintenance during this period.

Constant display on easy-to-read LCD

Bright and large LCD have been incorporated for the digital display of integrated flow and instantaneous flowrate values of all times. By utilizing such instantaneous flowrate value, flowrate adjustment of water supply and distribution can be easily performed.

Free installation position allows installation anywhere

Having no mechanical moving parts, the meter can be installed on a horizontal, vertical or inclined position, allowing installation anywhere with very little restriction for its location.

All stainless steel body with outstanding durability

Both the compact design wafer type (SU)* and easy-to-install flange type (SY) are made of all stainless steel body having the feature of long life. *The SU with 250, 300 and 350mm nominal diameters are flange types.

Flexible corresponding to various systems of specific use

Since these meters are equipped with electronic statement signal output function, installation of transmitter for specific use will enable flexible corresponding to various systems such as remote meter reading, automatic meter reading, as well as monitoring and controlling.

Features

A cost effective ultrasonic flow meter specialized for measuring air and nitrogen is now available!

It has realized a wide range of measuring ability and ZERO pressure loss using the characteristics of ultrasonic waves. It is also well-equipped to handle dust and mist and has excellent durability compared with conventional flow meters that use other measuring principles because it does not have moving parts.

The meter can be selected from two types of power sources: built-in batteries that can run 10 years without needing power construction, or an external power supply (24 VDC).

?To understand and visualize the usage of compressed air as a measure of saving electric power.. ?To understand the amount of nitrogen refined and used in a factory. (Can be applied to a degreasing treatment.)

Specifications

*1: In the actual flow measurement setting, the digits of the accumulated flow rate display, instantaneous flow rate display and pulse output vary. *2: When displaying the instantaneous flow (NL /min), the main display (accumulated flow rate), sub-display (instantaneous flow rate [Nm3/h]), pressure (kPa) and temperature (°C) will not be displayed. * Piping conditions: 20D or higher in upstream and 5D or higher in downstream for the 25A/32A models. (When using in the forward and reverse display mode, 20D or higher on both sides.) 10D or higher in upstream and 5D or higher in downstream for the 40A or larger models. (When using in the forward and reverse display mode, 10D or higher on both sides.) For more information, please contact our sales and branch offices.

AS-W Series

Since AS-W flow meter covers wider range from small to large flow rate, it contributes to cost saving and convenient facility management. At the same time, it saves the cost of redundant governor and piping.

? Non-moving parts results in not degrading meter performance. It eventually makes needless to repair the parts and refuel the lubricant oil.
? Because of the pressure loss being closely “0”, it can get rid of the pressure shortage risk.
? Because of lightweight and compact feature, it enables easy installation and needs less space.

Product Specifications

*1. The flow rate measurement range is ±5% RS: Inclusive before “∼” and not inclusive after “∼” and ±2% RS: Inclusive for both before and after “∼”.
*2. When the flow rate is less than 0.25% of the maximum flow rate, the instantaneous flow rate is indicated as 0 m³/h. For the normal conversion type, the low flow cut off value is the normal conversion flow rate corresponding to 0.05 m/s.
*3. Automatically switched in every 4 seconds.
*4. This flowmeter guarantees the flow measurement accuracy with the pipes listed in the table below.
(If you use pipes with the different pipe standard and size not listed in the table, the flowmeter may not satisfy the flow measurement accuracy. Consult us in advance if it is considered to use different pipes out of this range.)

Features

Turbine meters in the TBZ and TBX series were developed for controlling the gas consumption of each piece of equipment such as compact boilers and various industrial furnaces.

The products realize a smart design with a lightweight and compact body and support a wide range of measurement including maximum working pressure and maximum measuring flow rate.

Furthermore, the built-in 2-system pulse transmitters enable you to establish a remote meter reading system and an energy control system.

The TBZ series even corrects temperature and pressure to allow you to read gas consumption in the standard conversion condition.

The external power supply model TBX-D has been newly added to the lineup of the TBX series. You can choose the model that would best suit your applications for better usability.

Note) TBX30, TBX100, and TBX100F are CE compliant. (Collaborative development product with Tokyo Gas Co., Ltd.)
