1、真空計量罐圍尺法<br />　　該方法使用鋼卷尺緊密接觸所測量的聚丙烯測量罐的每個環板的每個位置的水平部分，并測量其周長以獲得圈板的內徑。<br />　　該方法是傳統的測量方法，只要標尺的精度滿足要求，測量方法合適，可以獲得良好的測量結果。由于該方法在測量時需要腳手架，因此耗時，勞動強度大，成本高，而且是高空作業，具有一定的不安全性。因此，通常不使用該方法。<br /> 2、真空計量罐械徑向偏差輪法<br />　　在該方法中，機械偏差輪在真空計量罐的測量母線上的運動用于觀察在罐直徑方向上與其連接的垂直線的相對位置的變化，從而獲得徑向偏差。獲得圈板的內徑。該儀器結構簡單，易學，但測量受風力的影響很大，具有一定的缺點，如高空作業不安全。分析和大量實踐表明，這種測量的準確性不能得到保證，不能滿足現代計量罐精度的要求。<br /> 3. 真空計量罐三角測量法<br />　　該方法是通過利用經緯儀的光學觀察軸瞄準聚丙烯測量槽的切線方向上的測量點，并同時測量角度和長度來確定罐環的半徑。<br /><p> 德陽市凱夫拉環?？萍加邢薰?，主營聚丙烯換熱器、pp儲罐廠家、真空計量罐、阻燃PP板、廢氣塔等防腐設備，多年專業防腐設備行業經驗，期待您的來電咨詢合作。</p><p style="text-align: center;"><img
