Helical Flow Meter

Product catalog summary

Overview: Flowtech Measuring Instruments Pvt. Ltd. specializes in the development of helical rotor positive displacement flow sensors, designed to replace oval gear flow sensors in applications where liquids are impure. These sensors are engineered for reliability and are ISO 9001:2015 certified.

Features:

High accuracy and resolution.
Pressure capacity up to 400 bar, with special ranges up to 1500 bar.
Independent of viscosity, suitable for 1 to 106 mm²/s.
Low pressure drop compared to other positive displacement meters.
Pulsation-free measurement, resistant to pulsating flows.
Corrosion-resistant materials and bearings.

Applications: These flow meters are ideal for use in systems involving polyurethane, polymers, fuel oils, petrochemical products, thixotropic fluids, fats, oils, hydraulics, water/glycol mixtures, crude oil, and various food liquids.

Technical Specifications:

Material: Enclosure made of S.S.-316/S.S-304, rotor of stainless steel/tantalum, shaft of hard stainless steel-316/carbide, and bearings of carbide with hard SS.BALL.
Accuracy: +/-0.25 /1% FSD with repeatability of 0.02%.
Maximum working pressure: 100/400/1000 bar.
Temperature range: -40 to 120/150°C.
Connection types: Thread (M) or Flange.

Pulse Output Sensor:

Power voltage options: 5VDC/12 V DC/24VDC.
Output signal: NPN open connector.
Battery operated meter with 3.3 V10AH lithium batteries lasting over 5 years.
Display: Double row LCD showing instantaneous and cumulative flow.
Power-fail protection for up to ten years.

Display with 4 to 20 mA Output: Offers optional outputs such as HART protocol, RS-485, and alarm functions.

Calibration Process: Each sensor is calibrated at three pressure points (0.5, 4, and 25 bar) using pure water at 25°C, with pulse/liter calculations at various flow rates.

Model Specifications: The document lists various models with line sizes ranging from 4 mm to 200 mm, each with specific flow rate ranges.

Dimension Drawings: Includes detailed dimension drawings for flange, T/C, and thread end connections.

900/2/B,GIDC MAKARPURA, VADODARA-390010 GUJARAT, INDIA. FLOWTECH developed and produced helical rotor Positive displacement flow sensor specially for replace oval gear flow sensor at some application where liquid is not pure and require easy and low weight flow meter ,Helical flow meters are positive displacement meters with a very favorable low pressure drop behavior. therefore perfectly suited for the flow measurement of very high viscosity fluids. Due to wide measuring ranges, high accuracy and resolution helical flow meters are an excellent choice for laminating systems, painting systems,...
