(1)	execute for and on behalf of the undersigned (in accordance with Section
16(a) of the Securities Exchange Act of 1934, as amended, and the rules
thereunder (the "Exchange Act")), any and all Forms 3, 4 and/or 5, and any
amendments thereto, that are necessary or advisable for the undersigned to file
under Section 16(a) (collectively, "Documents") with respect to the
undersigned's holdings of and transactions in the securities issued by Badger
Meter, Inc., a Wisconsin corporation (the "Company").

(2)	do and perform any and all acts for and on behalf of the undersigned that
may be necessary or desirable to complete and execute any such Documents and
timely file such Documents with the United States Securities and Exchange
Commission and any stock exchange or similar authority; and

(3)	take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall
contain such terms and conditions as such attorney-in-fact may approve in such
attorney-in-fact's discretion.

The undersigned hereby grants to each such attorney in fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that each such attorney in fact (or such
attorney in fact's substitute or substitutes) shall lawfully do or cause to be
done by virtue of this power of attorney and the rights and powers herein
granted.  The undersigned acknowledges that each attorney in fact, in serving in
such capacity at the request of the undersigned, is not assuming, nor is such
attorney in fact's substitute or substitutes or the Company assuming, any of the
undersigned's responsibilities to comply with the Exchange Act.

The undersigned agrees that such attorney-in-fact may rely entirely on
information furnished orally or in writing by the undersigned to such
attorney-in-fact. The undersigned also agrees to indemnify and hold harmless the
Company and such attorney-in-fact against any losses, claims, damages or
liabilities (or actions in these respects) that arise out of or are based on any
untrue statement or omission of necessary facts in the information provided by
the undersigned to such attorney-in-fact for purposes of executing,
acknowledging, delivering and filing Documents and agrees to reimburse the
Company and such attorney-in-fact for any legal or other expenses reasonably
incurred in connection with investigating or defending against any such loss,
claim, damage, liability or action.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Documents with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to each
of the foregoing attorneys in fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 19th day of March, 2017.
