FT-L-24-10 LEVEL MEASUREMENT AND DETECTION

Product catalog summary

Introduction
PROTAIS VIGIL, with over a century of experience, specializes in designing and manufacturing instruments for measuring physical quantities such as pressure, level, flow, and temperature. The company expanded its expertise in high-technology level measurement for nuclear, marine, and petrochemical applications by acquiring CORSET in the 1980s.

Level Measurement and Detection
The document defines 'level' as an instrument measuring the height of fluid in a tank from a reference level. It distinguishes between level detection, which signals when a predetermined height is reached, and continuous level measurement, which provides a proportional signal of the height.

Specifications for Level Instruments
To specify a level instrument, details such as fluid type, density, viscosity, temperature, pressure, tank shape, and presence of mixers are necessary. The document also highlights the importance of specifying whether the system is intrusive or non-intrusive, applicable standards, and whether local or remote reading is required.

Types of Level Instruments

Float Level: Simple, reliable instruments based on Archimedes' principle, used for local indication, measurement, or regulation. They require no external energy and can be made from various materials like stainless steel, titanium, and Teflon. They operate up to 250 bar and 260°C, with a minimum fluid density of 0.5.
Magnetic Float Gauges: Use a magnetic float within a metallic tube connected to the tank. Suitable for high-pressure applications and can be equipped with local or remote reading and alarm switches.
Hydrostatic and Electronic Levels: Part of the product range but not detailed in the provided text.

Float Level with Mobile Float (Series 12000)
This system uses a float on the fluid surface connected to a counterweight via cables. It provides local measurement for tanks up to 15 meters deep and can include electrical switches for alarms.

Magnetic Level Indicator (Series 14000)
Made of stainless steel or titanium, this indicator uses a magnetic float within a measuring tube. It is suitable for high-pressure applications and can be customized for specific needs.

Vertical Magnetic Level Switches (Series 20000)
These switches are typically made of stainless steel and can be customized in titanium. They are mounted on the tank's top wall and are suitable for temperatures from -40°C to +230°C, with a standard pressure use of 25 bar.

Vertical Magnetic Float Level Series 20000
These level switches are primarily made of stainless steel, with titanium options available. The float material can vary between stainless steel, plastic, or titanium, depending on the application. They operate with a minimum fluid density of 0.7 and a standard maximum working pressure of 25 bar, with higher pressure models available. The temperature range is from -40°C to 230°C, and they are mounted on the top of tanks. The electrical connection is rated at 250VAC/8A, with an IP65 or ATEX electrical box.

Lateral Magnetic Level Switches Series 20020
These switches are mounted on the tank's lateral wall and are made of stainless steel, with titanium options available. They can handle a maximum working pressure of 150 bar, depending on the tank's class. The temperature range is -40°C to 230°C, with a minimum fluid density of 0.7. They are commonly used in marine applications for reservoir balancing, with an IP65 electrical box and ATEX versions available.

Miniature Level Switch Series 60000
Designed for small tanks, these switches provide level indication and control for compatible fluids. They feature a stainless steel or plastic float, with a maximum working pressure of 10 bar and a temperature range of -40°C to 120°C. They are compact, with a shock resistance of 10g and electrical tension of 220VAC or 200VDC. The contact is typically a NO reed switch, with a capacity of 70VA AC or 70W DC.

Magnetic Float Indicator Series 21000CNR
This device provides local or remote level reading using a resistive electrical chain activated by a magnet in a float. It is made of stainless steel or titanium, with a measurement range of 0.4 to 5 meters and a maximum pressure of 30 bar. The output signal is 4-20mA, with a resolution of 20mm (10mm optional) and an IP55 junction box (IP65 on request).

Submersible Level Transmitter Series PVQYB200
Based on differential pressure measurement, this transmitter is suitable for fluids compatible with wetted materials. It features a stainless steel body, a level range of 0 to 100 meters, and an accuracy of 0.2%. The working temperature is -40°C to 80°C, with a power supply of 12-36VDC and output signals of 4-20mA, 0-5V, or 0-10V.

Level Indicator Series M25
Used for level measurement in tanks with compatible fluids, this indicator has an aluminum alloy body and a sensitive element made of copper alloy or stainless steel. It offers a level range in liters/m3/mm, with an accuracy of 1 to 1.6% and a working temperature of -40°C to 80°C.

Stromberg Transmitter Indicator
Designed for boiler tank level control in power plants, this device operates under high pressure and temperature conditions. It provides direct level reading and is built according to the pressure equipment directive 2014/68/EU. It includes a local indicator and a transmitter for remote data transmission.

Hydrostatic Level Measurement by Bubbling Series 11000
This method provides permanent level indication for various fluids, with local or remote measurement capabilities. It is suitable for tanks at atmospheric or pressurized conditions, with an accuracy of 1% and an operating temperature range of -20°C to 70°C.
