MEP 003 frequency meter

[m16ty]

Yea I was a little disappointed in how the meter didn't seem very weather resistant. What do you expect for $19 though.

I like how yours is out of the weather but I'd kind of like mine a little more assessable.

Triple jim can 3d print a plastic insert that goes in that hole and the meter will set it it. There is a post of his on here somewhere showing the piece and i think it was for the hardy meter. I cant remember. Send him a pm.

 

[Triple Jim]

I would offer to help, but the one my son printed from my drawing was for installing a small rectangular Hobbs hour meter in the round cutout. It was more of a fun project than anything else, since for making just one, it would have been faster to cut one out of aluminum.

 

[Jimc]

Oh yes it was the hour meter. For some reason i thought you had made that for the hardy meter. Oh well nevermind.

You can get a replacement meter that is similar or the same as the OEM. My 003 has A&M instrument gauges but I think some units also use Simpson. A new Simpson meter works directly on 120vac input, so no need for the transducer. It will fit the panel cut out and give it the OEM look. I have found them for $170,-it ain't cheap but after all the work some of us put in these units, it's really nice to have functioning gauges.

Personally, I am to OCD to not do it were my meter shot. I post some more info on the A&M meters in a day or two.

The part # is Simpson model 85, catalog #35162. (120VAC, 60 Hz, 55-65 scale, 3 1/2" rugged).

I have some 69-595 dual range matched sets,

Meter & Transducer, just waiting on my membership to be upgraded, mailed check 3/15 will list in parts for sale

I emailed Al Burill at Weschler Instruments about the panel meters. Here are the emails:

Hi John, do you want the front and back of the meter to be round or just the back? I assume the voltage input is 120V and you want to read frequency. We can offer the Simpson model 85, catalog 35162, price $179.00 and 3 weeks to ship. We can also offer the Yokogawa big look style meter, square front, round back, catalog 254350ANAN, price $131.00 and in stock. See attached for data sheets. Have a good day and thank you for choosing Weschler Instruments.

Thanks Al. I am looking for the round front. I see a couple more on your site. The A&M Ruggedized panel meter, 3 1/2 round analog and the Hoyt Industrial & Military panel meter

Can you give me a price, lead time and cut sheet on those as well? The A&M are the ones in the generators and mine requires the transducer. Do you have a price on the A&M transducers as well? And finally, does A&M make a 60hz 3.5" round, analog, frequency meter that does not require the transducer?

John, if you have a lot of money I will quote those also but the ones I quoted are the least expensive. If you don’t need a sealed ruggedized meter I would suggest you stay away from the other two because of cost. If your transducer is still good, do you know what the output is? It should be a low DC output. Could be voltage or current. I might be able to get you a sealed round meter for a little less money but not a lot less to read the output of the transducer. I do not have the info on the old A&M. I will tell you that the A&M would cost about $2500.00 if we could get it for that. Even if A&M made a self contained unit, the cost for one piece would be prohibitive. You could get a small enclosure and put the Simpson in a NEMA4X box and it would do fine. They have a pretty good seal on the front but cannot take water direct on it. Let me know what you would like to do. Have a good day.

[Jimc]

Wow $2500.

 

[johnray13]

Yea, I know. Makes the $179 look like a deal.

There are also some Chinese knock offs on ebay that look real close to OEM but I cannot find a 3.5" round 60 hz frequency meter. Every type of meter but round 60 hz.

I have seen these meters on the large auction site for around $40. The meters have a 200ua movement. usually the transducer goes south, the meter is probably ok if it shows no water damage. The capacitors in the transducers fail, and since they are sealed units, are hard to repair. An old analog Simpson 260 meter has a ua scale on it, those meters are fairly common. There are others, you just need a micro-amp scale to check the transducer output. 100ua, is approximately 60Hz. I hope this helps, and I haven't confused things more. If you can't borrow a multi-meter with the scale you need, I have a Fermont meter I could loan you to check the transducer and your meter.

I believe I'll stick with my $20 Hardy meter. I could buy 125 of them for the cost of one of the OEM ones.

Surely I can come up with a way to waterproof it to save $2,480.

 

[Jimc]

Haha yeah mine works great. That simpson meter isnt too bad price though and it looks original.

I picked up a MEP 003 last week. The unit fired right up but the frequency meter doesn't move. I have power coming out of the set so I'm thinking either my gauge or transducer is giving problems. I've searched and read threads that says a replacement is fairly expensive. What I'm trying to figure out is how to troubleshoot it to make sure what I need. All I've found in the TM says to check the gauge with another meter off the lugs and if they don't read the same, replace the meter and transducer.

I may just go with a inexpensive aftermarket meter but if I could troubleshoot this more and not have to have a new meter, I'd rather have it stock.

On e bay there is one on the auction.

I bought this meter, fit right in and no transducer for around $75 delivered.

 

[1800 Diesel]

I bought this meter, fit right in and no transducer for around $75 delivered.

Does that meter need the connection to the existing transducer or did you connect over to the terminals on the voltmeter? Just wondering because I just got an MEP003A that has a non-functioning freq meter. (Adjusted RPM & freq and verified with my multi-meter so I know the unit is producing proper current.)
Besides swapping out with a known-good meter, I'm not sure what else to do. If I can't figure out why the meter isn't working I may go the same path you did. Can you post a source for that one or pm me?

Thanks,

Kevin

I connected it to the terminals on the voltmeter.

It can be found on eBay and is sold by Hardy Diesel.

Thanks--I just ordered one of their digital freq meters just to have one in the house during generator running...will check out the analog one too...

 

[Harleyd315]

I'll try to dig up where i got from my old Amex bills tomorrow, there are ac wires that go to the transducer and dc coming out. I just spliced them together took the transducer out of the box and used the same wires that were on the old htz meter to connect the new one. works great

 

[Milspec33]

I had to find multiple gauges for my MEP 701a generators. I also found that the new A&M gauges were $$$. Coleman's and Delks Surplus will both pull meter and transducers from old gensets. It is a 50/50 shot if they work but they are OEM if that is important. I ordered 7 gauges from Coleman's and all arrived in good working order and for under $20.00 each! I have a MEP 002a that needs a transducer and I am trying to decide which course to take. Thanks for the good thread

Hello Harleyd315, I really like the analog frequency meter that you installed on your genset. I have searched high and low for the gauge you have with no success. Could you Please steer me in the right direction to purchase one of these gauges. I think your solution to elimate the frequency tranducer and original gauge and still utilize the same spot in the control board panel for the money was an excellent choice. Thank You for any and all help. Paul
