Pressure Rating:

TM Series meters are manufactured with 2 different pres-

sure ratings (though not in all sizes/materials). Pressure

rating is identified in position 11 in the Part Number:

Pressure rating applies to -40ºF/+100ºF (-40ºC/+38ºC) tem-

perature range. At higher operating temperatures the pres-

sure rating is reduced by factors shown below:

Temperature Rating:

TM Series meters are rated for use on liquids with tempera-

ture in -40ºF/+300ºF (-40ºC/+150ºC) range. This tempera-

ture rating applies to the flow meter only.

Electronic signal conditioner, totalizer or register attached to

the flow meter will have a different rating, which may differ at

both the low and high end of the range (refer to manual for

electronic components). When that is the case, the elec-

tronic component must be installed remote from the flow

meter.

Flow Meter Nominal Capacity:

TM02D 0.3 GPM 1.1 lpm

TM03 3.0

GPM 11 lpm

TM04 10

GPM 38 lpm

TM06 20

GPM 76 lpm

Actual capacity depends upon liquid lubricity, viscosity and

operating temperature. Normal turn-down is 10:1 from nom-

inal (maximum) value shown. Optimum performance is be-

tween 50% and 85% of nominal capacity.

When the viscosity exceeds 200 cSt, maximum flow rate is

restricted, but the flow meter will have satisfactory linearity

(accuracy) down to 2-3% of nominal capacity.

To determine model maximum capacity on higher viscosity

liquids, find the flow meter coefficient for maximum liquid

viscosity in table below, and multiply nominal capacity with

this factor.
