UTM20 Series Ultrasonic Transit-time Flowmeters
8.19 Initial Meter Setup
You can set up the meter using the UTM20 keypad or the SoloCUE Flow Device Manager software.
This document addresses procedures using the UTM20 keypad. To use SoloCUE, see the "SoloCUE
Flow Device Manager Installation Guide" available at www.badgermeter.com.
For in-depth parameter programming, see “Parameter Descriptions by Menu” on page 44.
1. Program the meter settings:
When using the keypad to set up the UTM20 meter to measure flow, press MENU/BACK to enter
the main menu. In the SETUP > METER menu, enter the pipe characteristics, transducer, mounting
and fluid, and record the calculated spacing as needed. Install transducer.See the transducer
user manual for instructions.
2. Check calibration:
In the SETUP > METER > CALIBRATION menu, select Field for the Factor Mode. Enter the
calibration and sensor factors from the transducers into the scale factor and sensor factor value.
3. Zero the meter:
Due to different pipe characteristics, the meter must be zeroed in order to maintain accuracy. The
recommended method is to stop flow and make sure there is no flow before zeroing the meter. In
situations in which that is not feasible, you may zero the meter while the flow is steady or enter
the zero manually. Based on ZERO MODE, the SET ZERO option will be selectable.
a. If ZERO MODE is set to NO FLOW:
Check that the pipe is full of liquid and not flowing. Flow must be absolutely zero.
Securely close any valves and allow time for settling to occur.
Select SET ZERO-NO FLOW and click OK to set the new zero.
b. If ZERO MODE is set to STEADY FLOW:
Check that the pipe is full of liquid and flowing at a steady rate.
Select SET ZERO-FLOW and click OK to set the new zero.
4. Select temperature sensor (energy models only):
In the SETUP > INPUTS/OUTPUT > RTD menu, select the temperature sensor type, range and
order for positive and negative energy calculations.
5. Select units:
In the SETUP > UNITS menu, select the units and format of flow rate, total and velocity, and for
energy meters the energy rate, energy total and temperature.
6. Set up the flow settings:
In the SETUP > METER > FLOW SETUP menu, select flow direction, low and maximum flow
cutoff, and minimum and maximum signal strength.
