Electricity is dangerous!
You can be injured or killed!
Improper installations can cause fire, injury and death!)
The fuse or over-current device in the service entrance equipment which limits current flow is the determining factor in the service's rating [assuming that the over-current protection is properly sized for the conductors used!]
Therefore, if the main fuses are 100 Amp, it is a 100 Amp service, even if it has 3 fuses. The exception to this is a service having more than one disconnect [allowed under the six-disconnect rule], wherein you might have a 100 Amp service with the largest fuse or breaker being 60 Amps! ... or two 100 Amp panels fed with a 200Amp cable - is it a 100 Amp or 200 Amp service?
Barring seeing a picture or being there physically, my guess is that you have a 100-amp service.
I can only guess what the "hydro meter" is.
Is there more than one meter?
It could be that the "hydro meter" is the off-peak service meter for your water heater power! [In the Philadelphia area, PECo has historically provided the option to have some loads powered through a second meter at a reduced rate, controlled by a clock or other means, which is shut off during peak demand hours.]

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS
WORK SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
a meter that contains water
something that measures water
Hydro means water in Latin
Yes. The meter is the property of BC Hydro and not the homeowner. The meter Housing is the home owners but not the meter.
something that measures water
No, each size service needs its own meter base.
No. If the rest of the service is in good condition.

Whether you have an overhead or underground feed, that section of the installation is referred to as Service Entrance Conductors. On an overhead installation, it includes the conductors on BOTH sides of the meter, from the service drop conductors (attached at the service head) to the service equipment LINE terminals. On an underground installation, it refers only to the conductors between the meter's LOAD side and the service equipment LINE terminals. The conductors on the LINE side of the meter come from a distribution transformer and are unbroken between the transformer and your meter.
Meter is just one meter while as - runniing meter means considering a length overall for example - take a road length of 20m 1m - a meter but considering 20 m togeter in a runninig process is called running meter
A watt is the rate that work is done when an object is moving at one meter per second, against a constant opposing force of one newton. Under this definition that would include hydro energy.
