Metal tube rotameter (metal tube float flowmeter) is a commonly used instrument for process monitoring, control, and measurement in industrial automation. It features a compact size, wide measurement range, and easy operation 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 a newly designed indicator, a 4-20mA remote signal output module, a switch signal output module, instantaneous and cumulative flow display, HART protocol, and MODBUS(RTU) bus. Custom configurations are available to meet user requirements: high-temperature and high-pressure design, selection of corrosion-resistant materials, and installation designs for various pipe types ensure the product's suitability for diverse field needs.

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

I. Brief Introduction:

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

Overview:

    Metal Tube Float Flow MeterThe (Metal Tube Rotameter) is a commonly used variable area flow measurement instrument in industrial automation process control. It features a small size, wide detection range, and ease of use. It can be used to measure the flow rates of liquids, gases, and steam, particularly suitable for low flow and low volume measurements. Over the years, the Metal Tube Float Flow Meter has been widely applied 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, a variety of 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 Mount TypeFlow meterFor sizes DN50 and below, choose T-type structures; for sizes above DN50, opt for spring structures.

Flowmeter Connection SpecificationsThe TF series metal tube float flow meter standard model adopts the GB/T9119-2000 flange standard, which can be customized according to customer requirements. Threaded and clamp connection methods are also available.

Indicator Selection:

Users can choose from on-site display, battery-powered, wired remote, intrinsically safe, explosion-proof, or HART protocol-enabled models based on actual site requirements. Detailed functional descriptions of various indicators are listed below.

Indicator Type

Instrument Function Description

M1 Model

Local pointer indicates flow rate; no power required, no 4-20mA remote transmission; optional flow alarm device; scale can be set to instantaneous flow value or percentage scale value.

M3 Type

Local digital display, battery-powered, no 4~20mA remote transmission, non-explosion proof. LCD displays instantaneous and cumulative flow rates; on-site buttons are used to view and modify relevant parameters. The battery can last for 6 months, and the battery should be replaced when the display shows the T character (battery model: ER26500, 3.6V, 7.5AH, -55℃~85℃).

M4 model

Electrical remote transmission, inherently safe design, explosion-proof marking ExdⅡCT6, optional HART protocol functionality. Powered by DC24V, features on-site pointer indicating instantaneous flow and digital display of instantaneous and cumulative flow. Two-wire system with 4-20mA output, panel equipped with 4 buttons for viewing and modifying internal parameters. Detailed instructions on page 18.



M5 model

Electrical remote transmission, explosion-proof design with ExdⅡCT6 marking, optional HART protocol functionality. DC24V power supply, local pointer indicates instantaneous flow rate and digital display for both instantaneous and cumulative flow rates. Two-wire system with 4-20mA output. The panel features 4 buttons for viewing and modifying internal parameters.
