Can I Use an MMC UTI If I Previously Used Another Brand Such as HERMetic or Tanktech?

The answer is yes, you can generally switch to an MMC UTI even if you have previously been using another brand, such as HERMetic or Tanktech. However, before making the switch, it is important to check the compatibility of your existing vapour control valve, connection, adaptor and UTI configuration.

For shipowners, ship operators, chief officers and marine superintendents, changing from one UTI brand to another does not necessarily mean that the entire tank gauging arrangement needs to be replaced. In many cases, the existing installation can be retained with the correct adaptor or connection arrangement.

Let’s look at what you need to know before switching to MMC UTI.

1. Is MMC UTI compatible with HERMetic and Tanktech?

MMC UTI is commonly used for measuring:

• Ullage – the distance between the reference point and the liquid surface.

• Temperature – the temperature of the cargo inside the tank.

• Interface – detection of the oil-water interface, particularly for identifying free water.

These functions are also available in established UTI systems such as HERMetic and Tanktech.

However, having the same measuring functions does not automatically mean that the equipment is mechanically interchangeable.

The important consideration is the connection between the UTI instrument and the vessel’s existing vapour control valve (VCV).

According to available MMC product information, suitable connection and adaptor arrangements can be provided for existing HERMetic and Tanktech installations.

2. Switching from HERMetic to MMC UTI

MMC offers adaptor arrangements for HERMetic vapour control valve installations, including the TS-C2 connection arrangement.

This allows the vessel to retain its existing valve arrangement while using a suitably configured MMC UTI.

Before purchasing, let us know:-

• The exact HERMetic vapour control valve model.

• Whether the existing connection requires a TS-C2 or another adaptor.

• The MMC UTI model and connection type.

• Whether the existing storage tube and accessories can be retained.

3. Switching from Tanktech to MMC UTI

MMC provides a connection solution for certain Tanktech installations, including the TVC-02 vapour control valve arrangement.

With the appropriate adaptor, it may be possible to install an MMC UTI while retaining the existing Tanktech valve.

However, compatibility must be checked against the actual valve and instrument configuration.

Before switching, let us know:-

• The Tanktech vapour control valve model.

• The existing storage tube arrangement.

• The required MMC adaptor.

• The MMC UTI model and connection specifications.

4. Do I need to replace the entire vapour control valve?

Not necessarily.

One of the advantages of choosing a suitable MMC UTI conversion arrangement is that you may be able to retain the vessel’s existing vapour control valve.

For example:

This approach can help reduce unnecessary equipment replacement, installation work and conversion costs.

However, the final arrangement must be confirmed by the equipment supplier or an authorised service provider.

5. Important things to check before purchasing MMC UTI

Although switching brands is possible, you should not assume that every component from one manufacturer will fit another manufacturer’s equipment.

Pay particular attention to these five areas:

1. Vapour control valve compatibility: Confirm that the MMC instrument can connect safely to your existing valve.

2. Adaptor requirements: Identify the correct adaptor for your existing HERMetic or Tanktech installation.

3. UTI model: Confirm whether you require an MMC USA or MMC Asia model, as their connection arrangements may differ.

4. Tape length and specifications: Select the appropriate tape length and instrument configuration for your vessel’s tank depths and cargo requirements.

5. Safety and certification: Ensure that the complete equipment arrangement is suitable for the intended hazardous-area operation and meets applicable vessel and classification requirements.

It is also important to understand that a compatible mechanical connection does not automatically establish compatibility of replacement tapes, probes, electronic components or spare parts. Always use the manufacturer’s approved components.

6. Why consider switching to MMC UTI?

There are several reasons a vessel operator may consider changing to MMC:

• Equipment flexibility: Suitable adaptor options can support conversion from existing UTI installations.

• Reduced replacement costs: Existing vapour control valves may be retained where compatibility is confirmed.

• Maintenance convenience: Operators can consider alternative equipment suppliers and service arrangements.

• Operational continuity: A properly planned conversion can help minimise disruption to normal cargo gauging operations.

• Supplier alternatives: Having another equipment brand available gives vessel operators more choices when sourcing equipment and spare parts.

7. Frequently asked questions

Q1: If I am currently using HERMetic UTI, can I change to MMC?

Yes. MMC offers adaptor arrangements for certain HERMetic installations. The correct connection must be confirmed before purchasing.

Q2: If I am currently using Tanktech UTI, can I change to MMC?

Yes. Certain Tanktech installations can be converted using suitable MMC connection arrangements, subject to compatibility checks.

Q3: Do I need to change my existing vapour control valve?

Not necessarily. Depending on the existing valve and adaptor arrangement, you may be able to retain it.

Q4: Can I use my old HERMetic or Tanktech UTI tape with the new MMC instrument?

Do not assume that the tapes are interchangeable. Different manufacturers may use different tape, electrical connection and sensor configurations. Confirm compatibility with MMC before reusing any components.

Q5: Can I use MMC UTI on different vessels with different existing UTI brands?

Potentially, yes. However, each vessel’s vapour control valve and connection arrangement should be checked individually.

Conclusion: Switching to MMC UTI can be a practical option

If your vessel is currently using HERMetic or Tanktech UTI equipment, you do not necessarily need to continue using the same brand.

MMC UTI can be a suitable alternative, provided that the correct adaptor, vapour control valve connection and instrument configuration are selected.

The most important thing is to check your existing installation before ordering the new equipment. This helps avoid connection problems, unnecessary replacement costs and operational delays.

If you are considering changing from HERMetic or Tanktech to MMC, it is advisable to provide us with photographs of your existing UTI, vapour control valve and connection arrangement so that the correct MMC configuration can be recommended.
