Find answers to the SRV/SRD Specifications related questions in this section – Operating Environment, Mechanical, Material Compatibility, Safety Approval, Shipboard Approval, Marketing & Branding, Installation & Use.
Operating Environment Specifications
What are the interdependencies between Pressure & Temperature range limits for the devices? i.e. can the instrument withstand 200 ⁰C and 5000 psi together? Please provide info on the pressure & temperature options that cannot go together. If there are certain other dependencies on Pressure/Temperature ranges, like limited Viscosity measurement range availability at higher pressure and/or temperature, please specify.
Does the Direct Meter Mount (solid tube between sensor & electronics) version for SRV/SRD share the same pressure and temperature spec limitations as the remote (via cable) meter mount version?
When mounted inline (withstanding radial flow), what are the limitations with regards to minimum & maximum flow rates? What are the limitations with other mounting arrangements?
Material Compatibility Specifications
Have you had any experience with exotic materials (e.g. Hastelloy-C, Inconel, Monel, other alloys) for process wetted parts?
Are any elastomers or O-rings used to isolate any part of the sensor from the process or the outside environment?
What are the extension length sizes/limitations for the Direct meter mount version of SRV/SRD instruments?
What are the allowable limits for solids contamination (particle size, concentration) in process fluid? Have you had experience with installing and using the instruments in slurry type applications?
Safety Approval Specifications
What are the exact Safety Approvals (ATEX / IECEx) markings the instrument can carry? If none, what is a realistically achievable target?
For the CE certification, which specific CE standards and directives do SRV/SRD devices comply to. Please share Declaration of Conformity cert if available.
Shipboard Approval Specifications
What stage is at the DNV-GL Shipboard approval process and what do you see as a realistic target date to receive DNV-GL certification?
Marketing and Branding
Do you see any issues if any company opts to sell and market SRV/SRD under a private label?
Installation and Use
Have you replaced an Emerson or a VAF unit in a working process installation? If so, how was retrofitting existing process connection handled?
For Marine Installations, is SRV device a drop-in replacement without changing the standard pipe spool housings that contain VAF and/or Emerson devices?
