典型響應(yīng)時(shí)間

40g/h-5kg/h<100 ms
1kg/h-600kg/h<200 ms

典型控制時(shí)間4

1. 密度讀數(shù)和密度精度與質(zhì)量流量讀數(shù)和質(zhì)量流量精度無關(guān).

2. 溫度讀數(shù)和溫度精度與質(zhì)量流量讀數(shù)和質(zhì)量流量精度無關(guān).

3. 當(dāng)質(zhì)量流量為40 g/h及更小時(shí),質(zhì)量流量的零點(diǎn)漂移為滿量程的±0.025%每攝氏度.

4.控制響應(yīng)時(shí)間與閥門選擇有關(guān),以上數(shù)據(jù)以spv01標(biāo)準(zhǔn)閥門為基礎(chǔ)。
