A guided wave radar level transmitter price is meaningful only when the finished probe assembly is defined. Two offers with the same nominal range may include different probe lengths, coatings, process connections and electronics. Compare the hardware that can actually be installed, not a family name followed by a distance.
Specify the probe before comparing the unit price
METRAVON MV-RD701 has rod and cable configurations. A cable's listed maximum length does not apply to the rod, and total probe length is not identical to usable measuring span. State the finished length from the defined reference and the highest and lowest levels that must be measured.
For chemical exposure, MV-RD702 introduces a covered probe construction. The offer should identify the covering, connection, seal and exposed end components. A coating name alone does not establish compatibility with the actual mixture or cleaning conditions.
Guided wave radar level transmitter price comparison
| Cost item | Compare on the offer | Why it matters |
|---|---|---|
| Probe | Form, finished length, covering and end treatment. | A field modification may not preserve the supplied construction. |
| Connection | Thread or flange detail, seal and process rating. | The instrument must fit and contain the actual service. |
| Electronics | Supply, output option and required interface information. | Similar housings can require different wiring. |
| Services | Drawings, application review, commissioning and documentation scope. | Exclusions can shift work to the installer after purchase. |
Include removal and installation work in the comparison
A rigid probe that fits inside the vessel may still be impossible to withdraw beneath a roof or pipe rack. Check probe removal and maintenance access before purchase. Isolation arrangements, access platforms and shutdown work belong in the project cost even when they are not supplied by the instrument vendor.
Compare quoted deviations line by line. An alternative material or shorter insertion length is not merely a discount; it changes the application. Close those differences with the responsible engineer before accepting the cheaper offer.
Q1. Is a longer cable always the only reason for a higher price?
No. Wetted construction, end sealing, process connection, electronics and required documentation can change the scope. Request an itemized configuration rather than attributing a price difference to one visible dimension.
Q2. Can standard stock be shortened after delivery?
Only under the procedure approved for that exact probe. A covered cable may have an end barrier that must not be damaged. Ask for the required finished length and any permitted adjustment before placing the order.
Summary
Request a guided wave radar offer with the vessel drawing, medium, process conditions, finished probe length and clearly separated supply and site-work scopes.
