TAILIEUCHUNG - Lưu lượng kế hơi nước kiểu Vortex

The SPIRAX SARCO Steam Meter consists of four basic parts. 1. M111 Transducer. This is installed in the steam line at the point where the steam flow is to be measured. (See TIS ). It is supplied complete with a 2m length of 8 core heat resistant cable for connection to the M322 Conditioning Unit. 2. EL2600 Pressure Transmitter. This provides a 4-20 mA analogue signal to the M322 Conditioning Unit proportional to line pressure for superheated steam applications (see TIS ). 3.

M111 Transducer. This is installed in the steam line at the point where the steam flow is to be measured. See TIS . It is supplied complete with a 2m length of 8 core heat resistant cable for connection to the M322 Conditioning Unit. 2. EL2600 Pressure Transmitter. This provides a 4-20 mA analogue signal to the M322 Conditioning Unit proportional to line pressure for superheated steam applications see TIS . 3. M322 Conditioning Unit. The function of this unit is to accept flow rate and temperature signals from the M111 Transducer and pressure signals from the EL2600 Pressure Transmitter and convert them to digital form for transmission to the M210G Computer. 4. M210G Flow Computer. This accepts signals from the M322 Conditioning Unit processes and displays them. The keypad enables the user to select the parameters to be viewed as well as allowing access to the numerous facilities available. See TIS . Note Wiring between Computer EL2600 Pressure Transmitter and Conditioning Unit to be provided by user installer. The SPIRAX SARCO Steam Meter is designed for use on dry saturated and superheated steam only. Flow rates are based on a max. flow velocity of 35m s. Correct installation is important if accurate and reliable flow metering is to be achieved. Full Installation Instructions are supplied with each unit. Basic essentials of good installation are shown overleaf. Commissioning and Operating Instructions are also available for each unit.
