本文档适用于TLS350R/TLS300系列
 
动态测漏



►CSLD – 持续静态测漏,通过大量短时测漏的结果,统计分析,判断油罐是否泄漏。 

►所需条件:
►►MagPlus1 or Mag1 探棒
►►控制台带有CSLD 模块
►►最短28分钟的静止时间,液位仪自动检测液面静止。

►功能:
►►在油罐静止期内自动工作,允许持续运行-无需人为设定测试时间;
►►满足EPA要求;
►►测试报告每24小时自动提供;
►►动态测漏算法自动筛选所有有效数据,并只使用最优质的数据进行测漏,从而减少误报率;

动态测漏结果的查看

 



 


测试结果解读


►PASSED  --     体积变化小于指定测试类型的限值

►PERIODIC TEST FAILED -  -所有测试条件符合的条件下,体积变化大于指定测试类型的限值

►INVALID  --     一个或多个测试条件不满足要求

►NO CSLD IDLE TIME    --   过去24小时没有足够的静止时间进行CSLD检测。建议静止一个小时。

►CSLD RATE INCR WARM – 油罐内液面上升

►NO RESULT AVAILABLE  -- 没有足够数据生成报告。在新开始CSLD是,需等待7~10天

问题

原因

措施

RECENT DELIVERY

A delivery occurred during the leak detect test or less than 8 hours before beginning the leak detect test.
测漏过程中有进油,或开启时间距上次进油结束小于8小时

Retest, waiting longer than 8 hours after last delivery
重新测试,进油后等待8小时以上再测漏

LOW LEVEL TEST ERROR

Fuel level is too low during a tank test.
测漏时油位过低

Call for delivery.
联系进油

FIRST LEAK PERIOD ERROR

 System was unable to obtain enough valid samples (150) to start a leak test during the first leak period (first half hour).
在开始的0.5小时内无法得到足够的有效样本

Call for service following the procedures established for your site.
 
根据加油站流程联系服务人员

LAST LEAK PERIOD ERROR

System was unable to obtain enough valid samples (150) to start a leak test during the last leak period (last half hour).
在最后的0.5小时内无法得5到足够的有效样本

Call for service following the procedures established for your site.
 
根据加油站流程联系服务人员

TEMPERATURE OUT OF RANGE

Temperature reading is below 0°F (-17.8°C) or above 100° F (37.8°C).
温度低于 -17.8°C或 高于 37.8°C

Wait for temperature to reenter the probe’s operating range.
待温度进入探棒工作范围内再测试

TEMP CHANGE TOO LARGE

Average temperature of all submerged thermistors changed by more than 0.1°F (0.06°C) per hour.
液面以下平均温度变化超过0.06°C/h

Retest.
 
 
重新测试

问题

原因

措施

CHANGE IN TANK TEMP ZONE

(Mag Probes only) A submerged thermistor’s temperature changed by more than 0.3°F (0.16°C) per hour.
液面以下有温度点变化超过0.16°C/h

Retest. If the problem continues, call for service following the procedures established for your site.
重新测试。如果依然发生此问题,根据加油站流程联系服务人员

CHANGE IN HEAD TEMP

(Mag Probes only)The temperature of the thermistor in the probe head changed by more than 1°F(0.6°C) per hour.
探棒电子头内部温度变化超过0.6°C/h

Retest. If the problem continues, call for service following the procedures established for your site.
重新测试。如果依然发生此问题,根据加油站流程联系服务人员

LEAK TEST TOO SHORT

A periodic test requires at least 2 hours to complete (3 hours for an annual test)
定期测试至少需要2小时(年度测试需要3小时)

Retest. For manual test runs, allow minimum test times. For programmed test runs, program a longer test time.
重新测试。对于手动测漏,要达到最小的测试时间;

PERCENT VOLUME TOO LOW

(Mag1 Probes only) Fuel level is less than the programmed minimum.
油品高度低于设定的最小值

Call for delivery.
 
联系进油

LOW LEVEL TEST ERROR

(Mag Probes only) Fuel level is too low, causing the fuel and water floats to be too close together.
油品高度过低,造成油浮子和水浮子相距过近

Call for delivery.
 
 
联系进油

PRODUCT LEVEL INCREASE

Fuel level increased more than the leak rate threshold value during the test.
测试过程中,油品高度上升超过限值

Call for service following the procedures established for your site.
根据加油站流程联系服务人员
