Handling Instructions

Observe the following handling instructions and precautions to obtain maximum performance of the Flowsensor / Flowmeter.

CAUTIONS IN MOUNTING

1. The flowing direction of the fluid, when mounting, must be matched to the arrow mark on the case that indicates the direction of flow.

2. A straight pipe with uniform inner diameter must be connected to the inlet. Accuracy is adversely affected if the pipe is bent or the inner diameter is uneven.

3. The inner diameter of the inlet pipe must be greater than the nozzle diameter of the Flowsensor / Flowmeter.

Type Inner D, of inlet pipe Length of straight pipe at inlet
ND05,NW05 5.5 mm or greater Greater than 50 mm from the end of the Flowsensor / Flowmeter
ND10,NW10 10.5 mm or greater Greater than 100 mm from the end of the Flowsensor / Flowmeter
ND20,NW20 15.5 mm or greater

4. If pulsation occurs in the flow of the fluid, measurement accuracy is adversely affected. When a pump is used to circulate the fluid, an accumulator must be provided to remove the pulsation.

5. Be careful not to apply excessive stress on the Flowsensor / Flowmeter during installation.

6. Make sure to provide thermal insulator at places subject to freezing in winter. When leakage occurs due to half frozen fluid, accuracy is adversely affected.

7. Do not expose/install the Flowsensor / Flowmeter under direct sunshine.

8. The measuring range, operating pressure and operating temperature are indicated on the plate on the side of the Flowsensor / Flowmeter. Observe these conditions for optimum performance of the Flowsensor / Flowmeter.

9. Avoid locating the Flowsensor / Flowmeter at places subject to excessive pressure and stress such as water hammer by operating components.

10. When air enters the Flowsensor / Flowmeter, measurement accuracy is influenced. Always operate the Flowsensor / Flowmeter chamber full of fluid. To maintain high accuracy, avoid mixture of air to the fluid.

11. Avoid placing a strong magnetic material or magnetic field near the Flowsensor / Flowmeter.

12. Installation position is flexible except those shown in figures on the upper right. However, it is recommended to install the Flowsensor / Flowmeter at the standard position whenever possible. For types ND 05-TATAAA, ND10-TATAAA, NW05-TTN, NW10-TTN, installation must be at standard positions.

Measurable fluids and parts materials

MEASURABLE FLUIDS

1.Fluid which done not corrode materials that contact the fluid.
2.Viscosity of the fluid to be measured is between 0.5 and 1.5cp.
3.No slurry is contained.
4.Particles attracted by magnetic power such as iron, is contained in the fluid.
(All of the above 1-4 must be satisfied.)
