Metal tube rotor flowmeters (metal tube float flowmeters) are commonly used process monitoring, control, and measurement instruments in industrial automation. They feature compact size, wide detection range, and easy operation and maintenance.
Product Execution Standards: JB/T6844, JJG257.
The TF series features all-metal construction with a transmitter that has 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 are available to meet customer requirements: high-temperature and high-pressure design, selection of corrosion-resistant materials, and installation designs for various pipeline types, ensuring 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 petrochemicals, metallurgy, electricity, 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 sensor material is standard 304 stainless steel (optional 316 or 316L). The indicator in the photo is a local pointer type. For horizontal flowmeters with an orifice size of ≤DN50, the T-type structure is commonly used. The indicator can be selected from other types according to on-site requirements.
Overview:
Metal Tube Float Flowmeter(The 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 rate and low volume measurements. Over the years, the metal tube float rotameter has been widely applied in industries such as petrochemicals, steel, power, 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 five types based on the direction of the fluid inlet and outlet: vertical type, horizontal type (further divided into 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 comes in standard, high-temperature, jacketed, and other versions.
Horizontal MountFlow meterWhen the diameter is less than or equal to DN50, use T-type structures; when greater than DN50, use spring-loaded structures.
Flow Meter Connection SpecificationsThe TF series metal tube float flowmeter 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 select on-site display, battery-powered, wireless remote, intrinsically safe, explosion-proof, or HART protocol-compatible indicators based on actual on-site requirements. Detailed functional descriptions of various indicators are listed in the table below.
Indicator Type
Instrument Function Description
M1 Model
Local pointer indicates flow rate; no power required; no 4-20mA remote transmission; optional flow alarm unit; scale can be set for instantaneous flow value or percentage scale value.
M3 Model
