Metal tube rotameter (metal tube float flowmeter) is a commonly used instrument for process monitoring, control, and measurement in industrial automation. It features compact size, wide detection range, and ease of use and maintenance.

Product Execution Standards: JB/T6844, JJG257.

The TF series features a full-metal structure transmitter with non-magnetic hysteresis and no mechanical transmission mechanism: The entire unit is based on modular design, including newly designed indicators, 4-20mA remote signal output modules, switch signal output modules, instantaneous and cumulative flow display, HART protocol, and MODBUS(RTU) bus. Custom configurations can be produced according to customer requirements: high-temperature and high-pressure design, selection of anti-corrosion materials, and installation designs for various pipeline types ensure the product's suitability for diverse field needs.

Metal tube rotameters, with their excellent performance, reliability, and favorable cost-performance ratio, are widely used in the measurement and process control of liquid, gas, and steam mediums in industries such as petrochemical, chemical, metallurgy, power, food, pharmaceuticals, papermaking, and water treatment.

I. Brief Introduction:

This series introducesHorizontal T-Type Metal Tube Float Flow MeterThe fluid inlet and outlet directions are left-in, right-out. The standard sensor material is 304 stainless steel (optional 316 or 316L), and the indicator in the photo is a local pointer type. For level flowmeters with a diameter of ≤DN50, a T-type structure is commonly used. Indicators can be selected from various other types based on site requirements.

Overview:

    Metal Tube Float Flow MeterThe Tube Rotameter (Metal Tube Rotameter) is a commonly used variable area flow measurement instrument in industrial automation process control. It features a compact size, wide measurement range, and ease of use. It can be used to measure the flow of liquids, gases, and steam, particularly suitable for low flow rates and low volumes. Over the years, the Metal Tube Float Flowmeter has gained widespread application in industries such as petrochemicals, steel, electricity, metallurgy, light industry, food, pharmaceuticals, and water treatment, thanks to its excellent performance, reliability, and favorable performance-to-price ratio.

Flowmeter Type:

The TF series metal tube float flowmeter consists of a measuring tube (sensor) and an indicator (electronic converter). By selecting different types of measuring tubes and indicators, various complete units can be assembled to meet on-site requirements.

The TF series metal tube float flowmeters are divided into 5 types based on the direction of the fluid inlet and outlet: vertical type, horizontal type (including horizontal T-type and horizontal spring type), bottom inlet side outlet type, side inlet side outlet type, and side inlet top outlet type. Each type also features standard models, high-temperature models, jacketed models, and so on.

Horizontal MountFlow meterWhen the diameter is less than or equal to DN50, choose T-type structures; for diameters greater than DN50, opt for spring structures.

Flow Meter Connection SpecificationsThe TF series metal tube float flowmeter standard model uses the GB/T9119-2000 flange standard, and the flange standard can be customized according to customer requirements; both threaded and clamp connection methods are available.

Indicator Selection:

Users can select from on-site display, battery-powered, wireless remote, intrinsically safe, explosion-proof, or HART protocol-compatible models according to their specific on-site needs. Detailed descriptions of the various indicators' functions are listed below.
