Frequently Asked Questions

Questions About Magnetic Level Gauges

How Does a Magnetic Level Gauge Work?
A Magnetic Level Gauge functions as a communicating vessel with the tank or system to which it is mounted. Inside the chamber of the Magnetic Level Gauge is a float. This float floats on the liquid, with most of it submerged in the liquid. At the liquid level, there is a Magnetic inside the float. This Magnetic controls the wafers in the display. As the float passes by, the wafers s flip from white to red, indicating the level. This magnetic field can also be used to operate switches and a transmitter.
Can Magnetic Level Gauges be manufacturedLevel Gauges my specifications?
Yes, Magnetic Level Gauges are manufactured to customer specifications. This means that every unit is unique.
What materials can a Magnetic Level Gauge made of?
A Magnetic Level Gauge can be made from any material that is non-magnetic (such as steel) and suitable for the application. Standard Magnetic Level Gauges are made of 316(L) stainless steel or 1.4401/1.4404 stainless steel. The float is made of 316Ti or 1.4571 stainless steel, titanium, or Hastelloy as standard. The unit and the float can also be made of plastics such as PVC-U, PVDF, PE, or PP, or of other materials such as Hastelloy, Monel, titanium, or 254SMO/6Mo, or be lined with ECTFE or PFA.
WhyLevel Gauge a Magnetic Level Gauge be made of steel?
Steel grades with a ferritic or martensitic structure can be magnetic and do not allow the float's magnetic field to pass outside the measuring tube.
What is the diameter of the chamber in a Magnetic Level Gauge?
The standard outer diameter of the chamber of a Magnetic Level Gauge is 2" or 60.3 mm. However, these can also be manufactured with diameters of 73.0 (2.5"), 88.9 (3"), or 114.3 (4"), giving you more space for the fluid or allowing you to mount a radar in a single unit.
Are Magnetic Level Gauges in accordance with PED?
Yes, Magnetic Level Gauges designed in accordance with the PED. Depending on the pressure and volume, they are marked with the PED logo.
Can Magnetic Level Gauges be ATEX-certified?
Yes, Magnetic Level Gauges can be certified to ATEX and IECEx standards.
I'd likeLevel Gauge custom version of my Magnetic Level Gauge . Is that possible?
Yes, any configuration is possible as longLevel Gauge the Magnetic Level Gauge continues to function as a communicating vessel.
What material is the display unit made of?
The display unit is made of aluminum as standard. The display unit's window is made of polycarbonate or glass. Other available materials for the display housing include 316 stainless steel or plastic.
Do you carry Magnetic Level Gauges stock?
No, Magnetic Level Gauge manufactured to customer specifications.
The Magnetic Level Gauge a different level than the other level measurements. How is this possible?
Inside the chamber of a Magnetic Level Gauge a float that floats on the liquid. This float is designed for the specific application. If the specific gravity of the liquid changes, the reading will deviate.
How accurate is a Magnetic Level Gauge?
A Magnetic Level Gauge a level indication. Changes in the specific gravity of the liquid, the pressure, and the temperature affect the reading. When taking a visual reading, allow for an accuracy margin equivalent to the height of 2 wafers approx. 2.5 cm).
What is the service life of a Magnetic Level Gauge?
Magnetic Level Gauges durable and have an expected service life of more than 15 years.
Does a Magnetic Level Gauge require (periodic) maintenance?
This depends on the application. For example, in some applications, material may solidify or build up on the inside of the chamber or the float. In these cases, (periodic) maintenance may be necessary.
How much does a Magnetic Level Gauge cost?
The purchase cost of a Magnetic Level Gauge vary widely, ranging from a few hundred euros to a few thousand euros, depending on the model and process conditions.
What are the advantages of Hadro Magnetic Level Gauges?
Hadro Magnetic Level Gauges the following advantages, among others: they are manufactured to customer specifications, are competitively priced, are easy to read, and require very little to no maintenance.

Questions about level switches

Can I install level switches on a Magnetic Level Gauge?
Yes, Magnetic Level Gauges can be equipped with solenoid switches. These can be mounted on both sides of the unit. You decide exactly how many you need. The switches can, of course, also meet explosion-proof requirements and may include a NAMUR output.

Questions about transmitters

Can I install an analog transmitter on a Magnetic Level Gauge ?
Yes, Magnetic Level Gauges can be equipped with level transmitters. These can also be supplied in Exi or Exd versions. The output can be in ohms, 4–20 mA, with optional HART 5 or HART 7, Profibus, or Fieldbus. We can also install a display so that you can read the level not only remotely but also locally, for example, in percentages or millimeters.

Questions about floats

How can I tell if the float is leaking?
Magnetic Level Gauges may be equipped with a float damage indicator on the bottom of the display unit. If this indicator turns blue, the float is leaking, or the chamber is empty. If the float no longer rises, even though you know there should still be liquid in the chamber, this indicates a leaking float.
The float on my Magnetic Level Gauge leaking. Can I order a new one?
Yes, that's possible. Always specify the process conditions, such as pressure, medium, specific gravity of the medium, and temperature. Also specify the inner diameter of the chamber of the Magnetic Level Gauge . You can also send a photo of the nameplate or provide us with your order number so we can immediately see what you need.
Do you keep rafts in stock?
Yes, we keep some floats in stock. If we don't have your float in stock, we can quickly manufacture and deliver it for you.

General Questions

What information do I need to provide to get a quote?
To prepare a quote, we always need at least the following information: medium, specific gravity of the liquid during operation, pressure, temperature, connections, center-to-center distance between connections, design standard (EN or ASME), and Ex environment.
