About Top Mounted Float Operated Level Transmitter

Top Mounted Float Operated Level Transmitter

Principle of Operation
Make level transmitter works on the principle of reed resistance/permanent magnet basis. Reed-switches function like the center arm of a potentiometer. As per liquid level float moves up or down, magnet inside the float operates the reedswitches thereby causing a change in resistance value. Change in the resistance is measured by the electronics unit and conditioned as a current output of 4 to 20 mA. Signal conditioner is head mounted and of 2-wire loop powered suitable for 12 to 24 VDC giving output of 4 to 20 mA.

Salient Features

Reedswitches are hermetically sealed-in glass under an inert gas and therefore protected from contamination.
Reedswitches used by us are suitable for maximum working voltage of 150 VDC and current 1 Ampere. But in our circuitry they are subjected to maximum of 3 VDC and current 1 mA in case of resistance output and maximum of 24 VDC and 20 mA when used in conjunction with a signal conditioner for current output. This ensures long life of the product.
Reedswitches are UL approved and ISO certified for quality management.
Operating temperature range of reedswitches are -40 ^oC. to 125 ^oC.
Reed Switches are enclosed in a moulded glass filled nylon capsule and therefore protected from mechanical shocks or damage. Moreover the stainless steel float-guide pipe, containing the PCB of reedswitches and resistances, is solidly filled with MgO Powder. Hence this is suitable for sub zero temperatures.
Reedswitches are protected against mechanical damage and contact corrosion & vibration.
Since an outer protection tube is provided (for applications like LPG, where external cage is not possible) the reedswitch sensor assembly can be replaced without disturbing the process.
Since the float is of 200mm dia with specific gravity -0.4 (for LPG) it will have higher buoyant force. For standard applications float shall be of 48 mm Or 68 mm in diameter.
Above all float is the only moving part. No wear and tear.

FAQs of Top Mounted Float Operated Level Transmitter:

Q: How is a top mounted float operated level transmitter installed on industrial tanks?

A: The transmitter is installed on the top of the tank using either flanged or threaded process connections. This flexibility allows for straightforward attachment, and the probe length can be customized to accommodate varying tank depths up to 5 meters.

Q: What types of liquids can this level transmitter measure?

A: It is suitable for a wide variety of liquids, including both corrosive and non-corrosive types. The use of stainless steel or engineering plastic housing materials ensures compatibility with aggressive chemicals commonly found in industrial environments.

Q: When is output from the transmitter available, and what is the signal type?

A: The transmitter provides a continuous analog signal in the 4-20 mA range, updating in less than one second. This output is compatible with standard industrial monitoring and control systems, enabling real-time level monitoring.

Q: Where can these level transmitters be used within an industrial facility?

A: They are used in various locations including storage tanks, process vessels, and sumps, wherever reliable liquid level monitoring is needed. Their robust design allows operation even in harsh, humid, or chemically aggressive environments.

Q: What is the process for customizing probe length or measurement range?

A: Customization is handled at the time of order. By providing the specific tank dimensions and application requirements, manufacturers can supply a transmitter with a probe length and measurement range tailored up to 5 meters.

Q: What are the main benefits of using this float operated level transmitter?

A: Key benefits include high accuracy (1% of full scale), rapid response, long-term durability, and compatibility with a diverse range of liquids. Its easy integration with automated control systems also supports optimal operational efficiency.

Q: How does the float mechanism ensure reliable level measurement?

A: The sensor features a magnetically operated float switch that rises and falls with the liquid level, providing precise and repeatable measurements through magnetic coupling, irrespective of liquid properties.
