Metal tube rotary flow meters (Metal tube float flow meters) are commonly used instruments for process monitoring, control, and measurement in industrial automation processes. They feature a compact design, a wide detection range, and easy operation and maintenance.
Product Execution Standard: 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, 4-20mA remote signal output module, switch signal output module, instantaneous and cumulative flow display, HART protocol, and MODBUS(RTU) bus. Custom configurations can be produced to meet user requirements: high-temperature and high-pressure design, selection of corrosion-resistant materials, and various pipeline installation designs ensure the product's suitability for a wide range of field applications.
Metal tube rotameters are widely used in the measurement and process control of liquid, gas, and steam mediums in industries such as petroleum, chemicals, metallurgy, power, food, pharmaceuticals, papermaking, and water treatment, thanks to their excellent performance, reliability, and favorable cost-performance ratio.
I. Brief Introduction:
This series introducesLevel T-type metal tube float flow meterThe fluid inlet and outlet directions are left in and 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 a diameter of ≤DN50, a common T-type structure is used. The indicator can be selected to be of other types according to site requirements.
Overview:
Metal Tube Float FlowmeterThe (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 is suitable for measuring the flow of liquids, gases, and steam, particularly for low flow rates and low volumes. Over the years, the metal tube float flowmeter 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-cost ratio.
Flowmeter Type:
The TF series metal tube float flow meter 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 (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 also includes standard, high-temperature, and jacketed versions.
Horizontal Mount TypeFlow meterFor diameters 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 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, wired remote, intrinsically safe, explosion-proof, or HART protocol-compatible models based on actual site requirements. Detailed functional descriptions of various indicators are listed below.
Indicator Type
