“NINJA” is a direct insertion type ultrasonic flow meter that can be installed to a pipeline using a maintenance valve
without stopping water flow. The flow meter can be easily installed and can measure micro flow velocity through its ultrahigh resolution measurement function.
The flow meter has functions of the integration of flow rate in positive and negative directions and the flow rate pulse output, which are impossible to deal with using an electromagnetic flow meter and can measure flow rate immediately without the need to install multiple measuring instruments.
ULTRA HIGH RESOLUTIONS
- Ultrahigh Resolution at 0.003m/sec both in positive and negative directions.
INDICATING SECTION
- The Indicator is connected to the “Sensor section” with a dedicated coupler cable. The Indicator sets various parameters (piping information, Measurement method and output).
SENSOR SECTION
- The sensor section consist of the ultrasonic sensor, shaft and control box, and can be installed into the center of the flow in the pipeline through the maintenance valve.
DYNAMIC AUTO – TUNING
- We’ve added a phenomenal function to our Caloriena & Ninja Models. Dynamic Auto-Tuning allows the user to calibrate without stopping the flow.
The controllers are able to automatically adjust or cancel zero offsetting, making installation even easier, just attaché, push On & start measuring!
ENERGY MANAGEMENT
The Caloriena is capable of measuring temperature. Therefore, it can also be utilized as a calorimeter. Energy consumption is a large issue in recent years. The Caloriena makes it easy to manage used energy or to organize energy conservation plans of even larger buildings.
MONITORING SYSTEMS IN VARIOUS FIELDS
Perhaps the most important characteristic of the Caloriena is how it attaches to pipelines without any holes or touching the fluid in question. This makes it the most sanitary, accurate and user-friendly ultrasonic flow meter on the market.
LEAKAGE DETECTION
Any leakage in a city’s water supply is a huge problem. Because of such leakages, huge amounts of funding are lost. However, it is extremely difficult to pinpoint the locations and details of a leakage.

Because the NINJA has an ultrahigh resolution and is also able to measure the smallest flow rates that canʼ t be detected by other flow meters, it is perfect for detecting these leakages. Specifically, you can use two NINJAs as a leakage-detecting unit. Furthermore, the NINJA can operate on battery power, so the flow meter can also be used as a portable detector. In fact, if a car battery (24 VDC) is installed, the NINJA can be used for a full week continuously.
SMART WATER GRID

The purpose of the Smart Water Grid is to efficiently monitor the supply and demands of water.
An ideal SWG will allow for the real-time monitoring of leakages. It should also be easy to find the specific details of such a leak. However, leakages can often result in only a micro-scale change in flow, making it difficult to find with a common flow meter. The NINJA, unlike the commonly used electromagnetic flow meter, is able to measure even these tiny differences in flow rate. This makes it a much more efficient candidate.
Moreover, A SWG often has parts in the pipeline that switch flow directions in the day and night or simply have sections of pipe where the flow direction is undetermined. An electromagnetic flow meter is unable to measure any flow in the negative direction, making it nearly impossible to operate a SWG efficiently. Conversely, the NINJA has the capability to measure flow rate in either direction.
The NINJA fits these important purposes of the SWG, making it the perfect product to efficiently manage water.
