Used for liquids such as water, diesel, solvents, low-viscosity chemical agents, and mineral oils (up to 46 cSt). Custom solutions are available for high temperature, high pressure, screw-in, flange, and other applications.
Based on the principles of turbines that have been proven in the past, fluid acts on the inclined surfaces of precision turbine blades, causing them to rotate. The movement at the tips of each blade is detected by sensors built into the main body of the measuring device, converted into pulse signals, and the frequency is then converted into flow rate. With a rated pressure of 3.5 MPa (maximum option of 34.5 MPa) and a rated temperature of 110°C (optional 232°C), it can accommodate many industries. We offer 12 sizes (0.7 L/min to 18,000 L/min) with either screw-type (straight G thread [male thread] or tapered R thread [female thread] up to 40 MPa) or JIS 10K-RF flange connections, allowing us to meet various customer needs. You can choose from three methods: 1] millivolt sine wave, 2] rectangular wave (square wave), or 3] 4-20 mA analog signal.

basic information
When the liquid flows and the internal rotor rotates, the sensor detects the movement of the blade tip and generates pulses. The frequency of the pulses is proportional to the flow rate and outputs the measurement. The signal can be combined with a transmitter that can be used for local displays, remote displays, or wirelessly transmitted to another control system. We can provide various proposals to meet all of our customers' requirements. All turbine flow meters are individually calibrated with water before shipment. A traceable certificate compliant with ISO, indicating the number of pulses per liter, is issued individually. The flow sensor is installed directly in-line with the piping, but to reduce turbulence and obtain the best measurements, it is recommended to install it in locations where there is straight piping of at least 10D in diameter upstream and at least 5D in diameter downstream. When there is a control valve, it should be installed on the downstream side, and to prevent the inflow of foreign materials that could block the line, it is recommended to install a filter before the flow meter. In environments with very long transmission distances or near electrically noisy equipment such as pumps, motors, generators, switchgear, and high-current cables, a preamplifier or shielded cables may also be necessary.
