1.6 Steam Traps that cannot be Evaluated
Although more than 1,000 trap models can be tested with TM, those that operate under the
following conditions cannot be evaluated:
1. Steam traps that are affected by high velocity steam flow noise.
a. Trap for TLV-COSPECT
(Pressure reducing and control valve with built-in separator and steam trap)
b. Trap for TLV-DC3S
(Cyclone separator with built-in steam trap)
c. Drip leg applications at pressure reducing stations and turbines.
2. Steam traps for very high pressures (greater than 80.0 kg/cm2or 999 psi) and
temperatures (greater than 350 °C or 662 °F).
a. Drip leg applications on high pressure boiler steam mains.
b. High temperature heat exchangers and reactor vessels.
(When these traps are to be inspected, manually input the results from other
measurement methods. Average leak levels will be used for steam loss
calculations).
3. High capacity steam traps with condensate discharge of more than 3,000 kg/hour or
6,600 lb/hr.
a. Large process equipment (heat exchangers, tank coils, etc.)
4. Steam traps that are used below 0.5 kg/cm2G (7 psig), or with differential pressures
less than 0.5 kg/cm2(7 psi); due to low ultrasonic wave frequencies of low velocity
leaking steam.
CAUTION
Some steam traps and products incorporating built-in steam traps are registered in
TrapMan, even though they cannot be judged properly due to the conditions stated above.
These models are registered for management purposes.

2. Functions and Features
Makes it possible for anyone to analyze steam traps easily
Measurement starts automatically as soon as the tip of the probe is pressed against the
measurement point. After about 15 seconds, measurement stops automatically and the
data is stored. After measurement is complete, the TM makes a judgement
automatically.
No handwritten notation is necessary at the site
Information about the operating and ambient conditions needed for steam trap
management can be entered directly into the TM unit and stored.
Data communication with the PC is easy
Simply connect the accompanying special cable and press the DATA TRANS key. No
complicated set-up process is required. Afterward, the communication process can be
easily performed on the PC while viewing the PC screen.
Possible to listen to the sound of operation using an earphone
The accompanying earphone can be used to listen to the sound of steam trap operation
(TM5N standard type only).
Battery can be charged in 2 hours
Approximately 2 hours of charging allows continuous operation for 8 hours (when back light
is used). The TM includes a function to prevent overcharging and a battery reconditioning
function.

3. Measurement Principles
3.1 Principles of Steam Leakage Judgement
3.1.1 TM measures ultrasonic waves
The conventional methods for steam trap diagnosis are surface temperature and sound. In
the past, sound audible to the human ear was used, but now that is being replaced by the
ability of the TM to detect ultrasonic waves humans cannot hear.
The advantage of using ultrasonic waves is that they are generated at the initial stages of
steam leakage, and are unaffected by surrounding noise. As a result, steam trap
deterioration can be detected at an early stage.
3.1.2 There is a correlation between ultrasonic waves and steam leakage
When steam traps leak steam, they emit ultrasonic waves. There is a correlation between
the intensity of the ultrasonic waves generated and the amount of steam leakage; however,
this correlation varies depending on the model of steam trap. The correlation formula will
also differ depending on the location at which measurements are made.
3.1.3 TM stores correlation with steam leakage according to trap model
Each correlation between the intensity of the ultrasonic waves and steam leakage is stored
in the TM according to the steam trap type. The TM can then use these correlations to
calculate the amount of steam leakage based on the intensity of the ultrasonic waves. The
inlet connection point is also fixed as the measurement point on each trap, allowing for
better correlation reliability, and automatic judgement of trap operation status.
3.1.4 Steam Loss Test Apparatus
Data onthe correlation between the intensity of ultrasonic waves generated and the amount
of steam leakage has been collected by TLV using the Steam Loss Test Apparatus at TLV
CO., LTD. headquarters. So far, data for over 100,000 cases has been collected in this
ongoing process.

3.2 Principles of Condensate Backup Judgement
3.2.1 Measuring inlet temperature of the steam trap
If the steam trap is operating properly, the inlet temperature of the trap will be almost exactly
the same as the saturation temperature of the steam pressure in that location. If blocked or
undersized, condensate will collect at the trap inlet and the trap inlet temperature will drop.
Accordingly, measuring the inlet temperature of the trap allows one to determine the
backup of condensate or the blockage status.
3.2.2 Comparing the calculated saturation temperature with the surface temperature
The correlation between saturation temperature and various steam pressures is stored
inside the TM hardware, enabling the saturation temperature to be calculated when a
pressure value is entered. By comparing the calculated saturation temperature with the
surface temperature measured at the trap inlet, the TM hardware is able to judge the
amount of condensate that has collected.
a) BLOCKED Judgement:
Measured surface temperature 40 °C (104 °F).
Made when the surface temperature at the trap inlet is less than or equal to 40 °C
(104 °F). (30 °C (86 °F) for temperature control traps.)
b) LOW TEMP. Judgement:
Measured surface temperature < saturation temperature 0.6.
Made when the surface temperature at the trap inlet is less than 60% of the saturation
temperature (for other than temperature-adjustable traps).
The reference value of 60% may be changed.
The criterion for judgement of LOW TEMP. "saturation temperature (up to but not
including) 60%" was set because there have been cases in past tests (that considered
the material and body thickness of each model of trap and external environmental
conditions) in which the trap surface temperature even at normal times generally
dropped by about 40% of the saturation temperature.
