Derwent James Ltd are UK agents for Badotherm instrumentation.

Throughout the world Badotherm supply our quality products and related services to EPC contractors and end users. Today, the concern is to ensure that you get good quality products, with proven materials, manufactured to international standards and have the assurance that they are suitable and measured up for the job.   

Badotherm manufacture and supply a full range of mechanical pressure and temperature process instrumentation. For service jobs, skids, and projects that contain a mixture of mechanical instrumentation, you can obtain all the following items from Badotherm.

These include a full range of:

• Pressure gauges: including process gauges, safety pattern gauges, differential gauges, and low pressure capsule gauges; and accessories over pressure protectors, swivel gauge adaptors, syphons;
• Diaphragm seals: flanged or threaded types in 316 S/Steel or exotic material that can be mounted to pressure gauges or transmitters; 
• Thermometers: including any angle types, both bi-metals and gas filled, direct, skin type or remote mounting;
• Thermowells: both threaded and flanged types as well as custom types, available with wake frequency calculations (ASME PTC 19.3);
• Needle or instrument valves and a variety of 2-way, 3 way and 5 way manifolds.

There are a number of important advantages in sourcing the complete package from Badotherm.

 1.     Badotherm are the specialist in mechanical instrumentation and advise you along the project and help you engineer. This prevents mistakes early in the project and helps save costs from the beginning.

2.     Using a single source you save time instead of placing and monitoring several orders on different suppliers and eliminate multiple administrative tasks.

3.     Badotherm complies with all relevant international manufacturing standards (EN837, ASME, etc) and strictly follows the requirements in the industry such as ATEX and REACH regulation, or regarding the material certification (2.1, 2.2. and 3.1 according EN10204) and NACE related requirements (MR01-75 / MR01-03) Additionally we can also host inspections and perform all kinds of (material) tests and certification such as calibration, dye penetrant, PMI, etc.

4.     Finally and possibly most important there is the peace of mind that by using one professional company (Badotherm) it ensures that that the various parts ordered match perfectly. For example it happens frequently when thermometers have been sourced from one source and thermowells from another and the diameter of the thermometers is too big for the thermowells or you have differential gauges that do not match the associated manifolds. By using one source for all this equipment you eliminate this worry. Badotherm will ensure that all the different parts are a perfect match.

Badotherm have had vast experience of numerous international projects over the last 25 years and are used by most major end users and contractors who all confidently specify and engineer Badotherm products and solutions.

Let Badotherm do the work for you and save you time, money and concern with the added assurance you will be getting quality products in a quality package.

Make Badotherm your professional partner for mechanical process instrumentation; we add value to your business.

Parameters that determine the design of a remote seal

• Location of the transmitter (indoor versus outdoor)
• Temperatures (process and ambient)
• Exposure to vacuum
• Pressure (operating and maximum)
• Length of capillary
• Type of seal desired
• Process connection, material of construction and similar considerations.
• Installation requirements
• Measurement span.

Ways to reduce measurement errors

• Seals with a large measuring diaphragm provide better results.
• The amount of error attributable to significant changes in either the process or ambient temperature varies widely with the combination of seal, capillary and fills fluid.
• Keep capillary lengths as short as possible.
• Never mount seals and capillaries in direct sunlight.
• Use capillaries of the same length on both taps when measuring differential pressure.
• Keep diaphragm sizes equal to both sides
• Be sure that both capillaries experience the same temperature. For instance, avoid installing one capillary in a shady area and the other in the sun. This eliminates zero shifts that results from unequal thermal expansion and contraction of the fill fluid in the high and low legs.
• The most common application of diaphragm seals is for level measurement. Proper ranging of a transmitter for level service requires considering the specific gravity of both the fill fluid and the process fluid.
• With dual-leg pressure transmitters, mismatched fill volumes (unequal lengths of capillary), degree of mismatch between seals (same sizes tend to offset any unbalance, though not completely) or uneven temperatures on seals and capillaries can affect the readings.
• Be careful with operators installing the application; for example, can easily cause a failure of a diaphragm seal simply by unscrewing the capillary.
• Another source of error is temperature effects. Although fill fluids are typically designed to minimize thermal expansion as much as possible, all fluids tend to expand as the temperature rises, increasing the pressure in the capillary and introducing an error.
• The volume of fill fluid should be minimized by using a capillary with a small bore and careful profiling of the seat behind the diaphragm.
• The specific gravity (SG) of the fill fluid itself can also introduce an error if the capillary extends vertically. This is a common problem in applications such as liquid level measurement
• It is important that the measuring range of the transmitter is sufficiently wide to allow the system to be zeroed to take any changes in level into account. Temperature variations will also have an effect here, because they change the density of the fill fluid.
• With GP / AP (gauge pressure and absolute pressure) transmitters mount diaphragm seals direct to the transmitter, if possible.
• With DP and AP, be sure that the lowest pressure (vacuum) at the transmitter side is always within the specification of the transmitter.

Diaphragm seals are used throughout the chemical and petrochemical industry to separate a pressure instrument from the process.  This protection enhances the lifetime of the measuring instrument significantly. However it can happen that the diaphragm eventually breaks. One of the advantages of diaphragm seals is that THEY CAN BE RENEWED, whilst RE-USING the pressure instrument. It will function just as a new instrument, but with the benefits of LOWER COST and a much SHORTER LEADTIME than buying a new instrument with seals.

Badotherm has been supplying this service for over 25 YEARS to its customers.

All brands of transmitters with diaphragm seals can be sent back to Badotherm because they operate independently of all transmitter manufacturers.

Urgent repairs can also be accomodated WITHIN 48 HOURS! in which they will provide a full assessment of the pressure instrument to improve its reliability and lifetime.

So if you have an urgent, difficult or unreliable pressure instrument then contact us today and we will ensure a SPEEDY COLLECTION of your pressure instrument with seals so a full assessment can be carried out by the Badotherm experts.
