What are float and tape type level gauges, and how does it work?

The float and tape type level gauge are famous for its reliability and delivers the correct level of indication continuously for all the mediums. Float and tape type level gauge is suitable for transferring the custody of the liquids in inventory management. This gauge has a float whose attachment is with the stainless-steel tape. Another end is on the drum (for storage), with the pulley carrying the spring constantly at the closing. The float keeps following the level of the liquid and stainless-steel twirls on the pulley. Its rotation transfers towards the pointer by the gear mechanism. It shows the correct level of the liquid on the dial. The float and tape type gauge availability is in stainless steel material and available with a guidewire to stop the movement of the float existing in the tank in the horizontal direction. The maximum temperature appropriate for float and tape type gauge is 120 degrees Celsius.

What are the features of float and tape type level gauges?

What is the principle of operation of float and tape type level gauge?

The float and tape type gauge is the float actuating tape driving by the gauge. A digital counter in the float and tape type level gauge shows the float is traveling correctly. The spring motor drum is in the float and tape type level gauge and stainless-steel spring that constantly supplies the power. The float and tape type gauge consists of stainless-steel tape, and the load distribution is perfect. This is because the bushing of the Teflon keeps rotating on the shafts that are the polish of stainless steel. A digital counter also displays the black figures on the white background of the float and tape type level gauge. You can also add reading remotely through the transmitter fix in the cover of the counter housing.

What are the installation guidelines for the float and tape type level gauge?

 

Installation of floating roof tank:

• Forward the end of the measuring tape in the floating head and tape type level gauge by the sheave elbow. Its location precisely on the top of float and tape type level gauge‘s head and forward the end of measuring wire in the tank. Join the looping end of the measuring tape with the drum of tape to tighten the screw.
• Keep pulling the measuring wire inside the tank, so there is the ring in a triangular shape whose connection is with the wire and elbow. It should be 150mm under the elbow of the sheave and cut down the measuring wire. You must make sure that it is more than 1.5M from the bottom of the tank.
• Place the float between the guiding rods so you can freely move it up and down. Then, fasten the float with the measuring wire.

 

Installation of the present tank:

• Whenever the fluid is in the tank, there is no possibility of welding. Therefore, you can anchor weight with the bottom of the anchor.
• Tighten one side of the guiding wire to the anchor’s weight along with the bolt and nut. Pass the other end with the guide ring of the float and fix with the top of the ring temporarily.
• The connection of one side of the measuring tape is with the float, and the other end is anywhere at the temporary location. It stops the tape from falling inside the tank while lowering the anchor.
• Move the bottom of the anchor downwards with the float and pass through the maintenance hole up towards the tank. Slowly release all the measuring tape and guiding wire.
• Fix the cover of the manhole on its position and keep pulling the guidewire. So, you can lift the anchor approximately 25mm from the surface.

How to set the indicator in float and tape type level gauge?

 

• Measurement of the level: Using the standard float and tape type level gauge, you need to measure the liquid twice or thrice to receive an average value. Then you can determine the readings on the counter or set indicator. Certify your float and tape type level gauge to obtain reliable and correct measurements.
• Adjusting the indicator: (dial and pointer type) whenever you remove the cover of the indicator from the head of the float and tape type level gauge, do loosen the nuts. This is because the more extended pointer keeps moving freely, and the shorter pointer can move quickly whenever it gets pulled in the outward direction.
• First, you need to set the shorter pointer on the division of the inner scale. It is adjacent to the lower two digits of the liquid level.
• It is now setting the more extended pointer at the division corresponding to the higher value digits by adding the two lower ones.
• Procedure for reading the indicator:
• It will help if you read a more extended pointer that shows the readings in the meter. Every division is equivalent to 100mm.
• The readings of the shorter pointer are in millimeters.
• Add up both the readings.

 

What are the limitations of float and tape type level gauges?

 

The common issue with the float and tape type level gauge is the hanging of the tap upside. This happens when the long guiding pipes are imperfect vertical direction wherever the taps are rubbing against in the pipes. One more problem in float and tape type gauge is dirt or corrosion that might happen in the pipe when the float keeps moving. This results in lower down readings than the actual ones. The force that the float’s weight applies reduces the friction present in the tape. The tanks that control the float and tape type level gauge overflows when the taps get jammed. To avoid this issue, you can use the high-level switch separately. Nowadays, the latest controllers are available that helps in monitoring the capacity of the tank and rate for pumping. It helps check the actual level, changing the direction and rate.

 

What is the reason for using the float guidewires?

The guidewires bring stability in the float in the disorder circumstances, and the accuracy level increases when there is a reduction in the horizontal movement of the float. In addition, there is the availability of accessories for installing the services, such as anchors for the weightage. It helps maintain the tension in the guidewires, and no need to do the welding in the tank. After installing float and tape type level gauge, you can use it for several operations and require periodic maintenance. The float and tape type gauge’s unique design is in a cylindrical shape that keeps floating on the surface of the liquid.

What are things present in the kit of the standard float gauge?

• Head of the gauge
• Float
• Tape for measuring

What are the requirements for the float and tape type level gauge?

 

• Power source: before connecting the float and tape type level gauge, you must check the power and voltage supply. Exact voltage must be available to work the float and tape type gauge properly.
• Using in the highly-corrosive areas: When using the float and tape type level gauge in hazardous surroundings, ensure all the instruments are explosive proof. In addition, take care during the installation process, wiring, and piping to ensure the safety of the float and tape type level gauge.
• External connectivity: when there is a requirement of external connection, protect float and tape type level gauge and ground it properly during the contact with the external controlling unit or some measuring object.
