PD 65A/PD 65B

• Cost-effective monitoring of single seal liquid leakage.
• PD 65 A utilizes a level transmitter fitted to the reservoir to trigger an alarm on excessive leakage and includes a loop to bypass an orifice (to prevent high pressure on the atmospheric side of the seal).
• PD 65B also uses a level transmitter, but to alarm when the reservoir is full, and includes a loop to bypass an isolation valve (to prevent high pressure on the atmospheric side of the seal).
