Overview

ENM’s series T56 LCD Vibration Activated Hour Meter. The hour meter features 6-digits with an hour glass icon as a running indicator. This unit operates only when it is introduced to vibrating equipment.

This meter can be installed anywhere on equipment with no special wiring connection or power source to operate. The internal battery supplies all the necessary power for the gauge to operate for years of service. The total operating hours are always shown on the LCD display.

This compact tamper proof meter is 100% encapsulated with potting compound enabling it to operate in even the most extreme conditions.

have had the ENM unit installed about 9 years. The battery final died. I have mine mounted with adel clamps on the motor mount of my I J-5. I have a friend that his is mounted on the instrument panel of his Champ. Both installations work great. I only have about 200 hours on the J-5 so I will mount ENM on a small fan and let it run for a couple of weeks to get the hours on the new unit back to 200. It is a simple effective device.

The hour meter works well I would have given it a 5 rating, except for the length of the wire. I connect a toggle switch in the wire, to assure that the hour meter only records when the engine is running and not when another vibration occurs. The wire on the back is so short that it is going to be problematic to install a toggle switch. The first ENM vibration activated hour meter I ordered several years ago had a longer wire and allowed for much easier installation of a toggle switch in the line.

It took quite a while (about two weeks) but the return of the item in exchange for a new one was good.

I have several of these in training aircraft that have not electric. One of them is at nearly 1000 hours in about 2.5 years and is working great. In another aircraft The second one just died. 200 hours on the aircraft and about 2 years or less on each hobbs. That is disappointing. I would give up the waterproof feature for a replaceable battery. I mount them on top of the instrument panel, no exposure to weather.

I bought this one to replace the original one ENM hour meter. that for some reason gets to 60.9 hrs and resets to 60.0. running up the hours on the new one will see if it can make it pasted 60.9

The internal battery is supposed to last 8 years (as marketed in the description), the hobbs meter died after about a year and a half. We were told the item only has a warranty for 1 year despite the claims made about its longevity. Dont waste your money.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Will this start running if the aircraft is re-positioned but not flown?

This meter is based off of vibrations. If the vibrations caused by moving the aircraft are great enough to simulate engine vibration then yes, the hour meter will begin running.

Q: Does the ENM vibration activated LCD hour meter require wiring through the firewall, or is it wireless?

No wiring is required.

Q: Might be good to state it has a wire loop on back that must be cut to be operational, but a switch can be placed in this wire loop so that when the switch is closed, the meter is non-operational, so it will not run when parked outside or moved around.

Thank you for providing this information, we will post it for other customers.

Q: Is this ENM Hourmeter (hobbs) 100% self contained?

Yes that is correct.

Q: Is this approved for certified aircraft or only experimental?

This is for experimental aircraft only.

Q: Is there a way to set the meter to the existing time on the engine? Can we have it shipped with our current number of hours already registering?

This model cannot be set to existing time. We do offer part # 10-07370 which can be set. However, please keep in mind part # 10-07370 is not vibration activated.

Q: Can the battery be replaced on the unit after it dies?

Per Vendor: "Sorry, no. These units have potting compound sealing them for environmental protection making the battery non-replaceable."
