I am assuming that you really want to use ammeters to measure power in a balanced 3 phase system. (hope you are not meaning 3 watt meter method)
Power in Watt in a three phase system is equal to 1.73 x line voltage x line current x power factor. You need to know line voltage, power factor also in addition to current to compute the power. If the system is balanced then actually you do not need to connect ammeters in all three lines. One ammeter reading will do.
a dc ammeter is a ammeter which has three pins and it works by two wires.
This is too complicated to describe on this forum, but there are lots of web pages that describe the 'three-ammeter' method of measuring power, so your best plan is to visit one of those sites.
You use three CTs, one per line conductor, each feeding a separate ammeter,
An ammeter measures current, an important variable in electronics.
An ammeter measures amperage not voltage.
single phase power measure by three ammeter method

dc ammeter has three connecting pins while ac has four
Voltmeter, ammeter, wattmeter.
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
You use three CTs, one per line conductor, each feeding a separate ammeter,
if we take resistance in parallel with ammeter then the range of ammeter will change.
ammeter real picture
An Ammeter and a brick is a brick.
How do you connect an ammeter to a circuit?
connect ammeter in series with load.
