，須***選擇防爆型，并按防爆要求進(jìn)行安裝使用
。">4, for the remote type instrument, we must first ensure that the instrument wiring correctly, keeps power; for dangerous situations, must choose the explosion-proof, and the installation and use of proof required by the.
、結(jié)構(gòu)分類說明：">Seven, structure classification:
1, the high temperature structure (G type)
。">High temperature structure type (G type) is used for medium temperature is too high or too low and the need to take measures on the insulation of the measuring tube medium flow measurement.
、增加隔熱材料厚度，保證指示器工作在允許的環(huán)境溫度范圍內(nèi)
。">The high temperature structure is increased and the distance between the measuring tube indicator to increase heat dissipation and increase the insulation thickness, ensure the working environment temperature indicator in the allowable range.
。">The selection of the "G" type.Flow type G metal tube rotameter can measure the temperature of -80 DEG -+300 DEG medium. 、帶阻尼器裝置的結(jié)構(gòu)（Z型）">The structure of 2, with a damper device (Z type) ，特別是對于氣體的測量 。">Damper structure type flowmeter for entrance flow (pressure) medium flow measurement is unstable, especially for gas measurement.
3, jacket type structure (T type) 。">Jacket structure for heating or cooling of needs (such as high viscosity and flow measurement of the medium Yi Jiejing). ，使低沸點(diǎn)流體不汽化和不結(jié)晶。">In the jacket by heating or cooling medium, low boiling fluid and vaporization crystallization.Import and export with thermal medium connection standard to use HG20594-97 DN15 PN1.6 flange, flange connection and other specifications may be marked with production plant, pressure rating jacket for 1.6MPa. 、外形尺寸圖 。">Jacket type flowmeter structure see FA standard flange type flowmeter and the size of map.
4, high pressure type structure (Y type) 。">High pressure type structure for media pressure is greater than the standard pressure level measurement. 。">High pressure type structure as shown below.At present, the maximum pressure can reach 32MPa FFM64 series. ，安裝高度均為350mm 。">In addition high pressure type flowmeter can provide built-in magnetic filter type, installation height is 350mm.
。">FA, FB and FC type maximum pressure of 10MPa. 、故障排除方法：">Troubleshooting eight fault: 。">1, check the alarm set value size SU. 、檢查偏差設(shè)定d值不能太大。">2, check the deviation set D value can not be too large. 、FUN功能中 ，邏輯功能是否正確。">3, FUN function, logic function is correct.
。">HA-A said the upper limit is logical.LA-A said the lower limit is.、線路板故障，更換線路板。">4, circuit board failure, replace the board.
、若液晶條碼指示正確，輸出無動(dòng)作，可檢查外部電源及外部電源的負(fù)極是否與儀表供電的負(fù)極相連。">5, if the lcd barcode indicates the correct output, no action, the cathode can check the external power and external power supply is connected with the anode of instrument power supply.、劇烈抖動(dòng)：主要由于介質(zhì)脈動(dòng)
，氣壓不穩(wěn)或用戶給出的氣體操作狀態(tài)的壓力、溫度
、流量與儀表實(shí)際的狀態(tài)不符
，有較大差異造成儀表過量程。">3, severe jitter: mainly due to medium gas pulsation, operation pressure instability or give users pressure, temperature, flow meter and the actual state does not have large differences over range instrument.
。">Nine, installation requirements.
