OCT 2013 DANIEL™ SERIES 1500 TURBINE METER
OPERATION4-2
4.3 Operation
Flow and pressure information is stamped on the nameplate located on the outside of the meter.
PERSONAL INJURY AND/OR EQUIPMENT DAMAGE
Never subject the meter to flow or pressure ranges above those specified in Section 2.0
Specifications, or those stamped on the meter.
Exceeding the meter specifications could result in serious injury and/or damage to the
equipment.
1. Back pressure at the outlet of the meter must be sufficient for proper operation. Consider the
following equation when determining back pressure for the meter.
2. P
b
= 2 ªp + 1.25 p
e
Where
P
b
= minimum back pressure, pounds per square inch gauge (psig)
ªp = pressure drop through the meter at the maximum operating flow rate for the
liquid being measured, pounds per square inch (psi)
p
e
= equilibrium vapor pressure of the liquid at the operating temperature, pounds
per square inch absolute (psia), gauge pressure plus atmospheric pressure
3. Valves should be opened slowly in such a way as to prevent system shock.
4. Care should be taken to protect the Series 1500 housing and components from external
impact of any kind. Note temperature limitations, Section 1 when selecting meter location.
