Professional Metal Tube Rotameter Manufacturer

Instruthinkmetal tube rotameter is suitable for small flow ranges with high accuracy. Its display can be a mechanical pointer or LCD digital display. If digital metal tube rotameter, it can send 4-20ma output and have RS 485. It can also be equipped with a limit switch and alarm. Instruthinkmetal tube rotameter consists of a tapered tube, inner float, and display part. Each part is made by ourselves, from electric board to float, so the delivery time is fast, there is enough raw material in stock. Usually, it is 3-4 working days for standard products.

1. What is a metal tube rotameter?

Metal tube rotameter is a variable area flowmeter that measures the spontaneous flow rate of liquids, gases, and steam applications. A metal tube rotameter is suitable where a normal rotameter cannot withstand demanding pressure and temperature constraints. Metal tube rotameter is best for measuring opaque fluids under high pressure and temperature.

Metal tube rotameter can measure the liquid and gases of density up to 2.95. The temperature range is up to 400°C, and the design pressure range of up t0 25 kg/cmآ² and has a measuring range of 100 to 40,000 LPH of water/Liquid 3.3 to 1400 Nmآ³.

2. How does it work?

The metal tube rotameter works on the variable area principle, in which the fluid increases the float in the tapered tube and increases the area of the fluid passage. The float moves through the linkages and counterweight. The float moves through the tapered tube upward and downward with the movement of fluid flow. The tube and float combination determines the flow rate.

There is a high magnetic field detections sensor that detects the inner float magnetic field. The metal tube rotameter does not need any electrical connection as it operates on a battery and has a built-in two-wire transmitter that takes 4 -20 ma signals.

3. What are the specifications of the metal tube rotameter?

Metal tube rotameter measures the flow of liquid and gas under critical conditions. It consists of a tapered tube, assembly, float, and rotating magnets that connect with the pointer. The movement of the float is measured in terms of flow rate. It has the material of SS316, SS316L, SS304, and titanium. It has the protection class IP-65 and IP-66. Also, you can customize the protection on request.

The metal tube rotameter has a repeatability of 0.5% and a scale length of 90آ°angular. It offers the accuracy range of 2% of total flow,1.5% of full flow (optional), or customizes the better accuracy for your application. The fluid temperature ranges from -20° to 100°.
